Question: How can I customize my log files in Elastic Beanstalk?

I want to customize my log files in AWS Elastic Beanstalk, and be sure that my custom application logs are included and streamed to Amazon CloudWatch.Short DescriptionIf the default log files that Elastic Beanstalk collects and streams don't meet the needs of your application or use case, then consider the following options to customize the collection and streaming of your log files:Include your custom logs in the log bundleRotate your logs(Optional) Stream your logs to CloudWatchNote: If you have a custom log file or if one of your logs is missing from the default logs, then you can further customize your log configuration.

ResolutionInclude your custom logs in the log bundleWhen you request logs from Elastic Beanstalk, Elastic Beanstalk returns default log files from the Amazon Elastic Compute Cloud (Amazon EC2) instances in your environment. However, you might not receive these default log files if your application has a unique log location.To get Elastic Beanstalk to return your log files from a unique log location, extend the default log task configuration.Rotate your logsTo prevent your application log files from taking up too much disk space or even exhausting disk space, rotate your old log files with log rotation.Rotating your logs makes sure that old logs are deleted automatically from your environment's EC2 instances. If you want your old logs to persist, you can enable rotated logs to be uploaded to Amazon Simple Storage Service (Amazon S3) before the logs are deleted from an instance.(Optional) Stream your logs to CloudWatchIn production applications, it's a best practice to stream your logs to a remote storage solution, such as CloudWatch. To learn how to enable log streaming on Elastic Beanstalk, see Streaming Log Files to Amazon CloudWatch Logs or Using Elastic Beanstalk with Amazon CloudWatch Logs.If you want to stream custom log locations, see Instance Log Streaming Using Configuration Files.Streaming your logs to CloudWatch can help safeguard your data. For example, if your Elastic Beanstalk environment has a problem with an EC2 instance that terminates, then you can still recover your logs from CloudWatch. You can also use log rotation to protect against data loss.Related InformationWhat Is Amazon CloudWatch Logs?Troubleshooting CloudWatch Logs IntegrationStreaming Elastic Beanstalk Environment Health Information to Amazon CloudWatch Logs

Question: Why am I getting the "CROSSSLOT Keys in request don't hash to the same slot" error while doing multi-key operations on a Redis (cluster mode enabled) ElastiCache cluster?

Why am I getting "CROSSSLOT Keys in request don't hash to the same slot" error while doing multi-key operations on an Amazon ElastiCache for Redis (cluster mode enabled) cluster even though the keys are stored on the same node?Short descriptionThis error occurs because keys must be in the same hash slot and not just the same node. To implement multi-key operations in a sharded Redis (cluster mode enabled) ElastiCache cluster, the keys must be hashed to the same hash slot. You can force keys into the same hash slot by using hashtags.In this example, the following sets, "myset2" and "myset," are in the same node:172.31.62.135:6379> scan 01) "0"2)  1) "myset"    2) "myset2"But a multi-key operation isn't supported:172.31.62.135:6379> SUNION myset myset2(error) CROSSSLOT Keys in request don't hash to the same slotThis is because the keys aren't in the same hash slot. In this example, the two sets are in two different slots, 560 and 7967:172.31.62.135:6379> CLUSTER KEYSLOT myset(integer) 560172.31.62.135:6379> CLUSTER KEYSLOT myset2(integer) 7967ResolutionMethod 1You can use a Redis client library that provides support for Redis (cluster mode enabled) clusters. For more information about Redis clusters, see theredis-py-cluster website.For example, using redis-cli returns the CROSSSLOT error when used to get keys from slots located in different shards:redis-cli -c -h RedisclusterCfgEndpointRedisclusterCfgEndpoint:6379> mget key1 key2(error) CROSSSLOT Keys in request don't hash to the same slotUsing the redis-py-cluster to get keys from slots located in different shards returns the correct output:>>> from rediscluster import RedisCluster>>> startup_nodes = [{"host": "RedisclusterCfgEndpoint", "port": "6379"}]>>> rc = RedisCluster(startup_nodes=startup_nodes, decode_responses=True,skip_full_coverage_check=True)>>> print(rc.mget("key1","key2"))Method 2When creating keys that are used by multi-key operations on a cluster mode enabled cluster, use hashtags to force the keys into the same hash slot. When the key contains a "{...}" pattern, only the substring between the braces, "{" and "}," is hashed to obtain the hash slot.For example, the keys {user1}:myset and {user1}:myset2 are hashed to the same hash slot, because only the string inside the braces "{" and "}", that is, "user1", is used to compute the hash slot.172.31.62.135:6379> CLUSTER KEYSLOT {user1}:myset(integer) 8106172.31.62.135:6379> CLUSTER KEYSLOT {user1}:myset2(integer) 8106172.31.62.135:6379> SUNION {user1}:myset {user1}:myset21) "some data for myset"2) "some data for myset2"Now that both sets are hashed to the same hash slot, you can perform a multi-key operation.
Question: How can I register a domain in Route 53?

I want to register my domain with Amazon Route 53.

Short descriptionBefore registering a domain in Route 53, verify that the TLD is supported by Route 53 and review the associated cost implications. For more information, see Registering a new domain.Note: Be aware when registering your domain name that you can't change the name after you register it. If you register an incorrect domain name, you must register another domain name and specify the correct name. Refunds aren't given for a domain name that you registered incorrectly.

ResolutionFor a list of TLDs that you can use to register domains with Amazon Route 53, see Domains that you can register with Amazon Route 53.For a step-by-step guide on registering domain names, see How to register a domain name with Amazon Route 53.For information on transferring a domain to Amazon Route 53, see Transferring registration for a domain to Amazon Route 53.

Question: How can I use an Application Load Balancer to route requests based on the source IP address?

I want to use an Application Load Balancer to perform specific actions on requests based on the source IP address of the request.

ResolutionThere are several use cases for performing specific actions based on the source IP address of a request. For example, you have two versions of an application. One version is a public version that's for global users. The other is an internal version that includes some extended (beta) features. You want the internal version to be available only to employees who are accessing the application from corporate network CIDRs. To accomplish this, and other similar tasks, configure listener rules based on source IP addresses.A rule that's based on source IP address checks the source IP address in the IP header (layer-3). If there's a proxy or firewall that changes the source IP address, then specify the proxy or firewall's IP address in the listener rule.Note: Don't use listener rules to block requests from clients. It's a best practice to use security groups or network access control lists instead. To block a large number of clients, you can use AWS WAF.1.    Create an Application Load Balancer. Or, use an Application Load Balancer that you already created.2.    Open the Amazon Elastic Compute Cloud (Amazon EC2) console.3.    On the navigation pane, under Load Balancing, choose Load Balancers.4.    Select your load balancer.5.    Choose the Listeners tab.6.    Select your listener, and then choose Actions. Then, select Manage rules.7.    Choose the Add rules icon (the plus sign), and then choose Insert rule.8.    Choose Add condition, and then choose Source IP.9.    Specify the IP addresses that you plan to configure a different action for.Note: You can specify either a single IP address or network CIDRs with prefixes. For example, specify 1.1.1.1/32 or 10.8.0.0/21.10.   Choose Add action, and then select the required action. See the following examples of actions:Forward: This forwards the request to a different target group, such as a target group that runs an internal version of an application.Return fixed response: This blocks specific users or provides custom responses to specific users.12.   To save the condition, choose the checkmark icon.13.   To save the rule, choose Save.

Question: How can I identify Availability Zones using AWS Resource Access Manager?

I want to identify the Availability Zone (AZ) ID using AWS Resource Access Manager (AWS RAM).

Short descriptionAWS maps Availability Zones to names for each account to be sure that resources are distributed across the Availability Zones of a Region. For example, the Availability Zone us-east-1a for your AWS account might not have the same location as us-east-1a for another AWS account.

ResolutionTo coordinate Availability Zones across accounts for VPC sharing, use the AZ ID. For example, use1-az1 is one of the Availability Zones in the us-east-1 Region.To find the AZ IDs for the Availability Zones in an account:Open the AWS Resource Access Manager console.In the navigation pane, choose Resource Access Manager.Under Your AZ ID, view the AZ IDs for the selected Region.Using the AZ IDs, determine the location of resources in one account relative to the resources in another account. For example, if you share a subnet in an Availability Zone with an AZ ID of use-az2 with another account, the subnet is available to that account in the Availability Zone whose AZ ID is also use-az2. You can find the AZ ID for each subnet in the Amazon Virtual Private Cloud (Amazon VPC) console.For more information, see Availability Zone IDs for your AWS resources.

Question: How do I assign a static hostname to an Amazon EC2 instance running Ubuntu Linux?

I changed the hostname of my Amazon Elastic Compute Cloud (Amazon EC2) instance. However, when I reboot or stop and then restart the instance, the hostname changes back. How do I make the new hostname to persist?Short descriptionTo be sure that the hostname persists when rebooting or stopping and starting your instance, add the hostname to the appropriate configuration files on your instance.Note: The following steps apply to Ubuntu Linux. For instructions that apply to other distributions, see one of the following:Changing the system hostnameHow do I assign a static hostname to an Amazon EC2 instance running RHEL 5 or 6, CentOS 5 or 6, or Amazon Linux?How do I assign a static hostname to an Amazon EC2 instance running SLES?How do I assign a static hostname to an Amazon EC2 instance running RHEL 7 or CentOS 7?Resolution1.     Use vim to open the /etc/hosts file.sudo vim /etc/hosts2.     Update the /etc/hosts file to include your persistent hostname for localhost, similar to the following:127.0.0.1 localhost persistent-hostnameNote: You might have to create an entry for localhost if the /etc/hosts file on your EC2 instance doesn't have an entry for it.For more information about the hosts file on Ubuntu, see the Ubuntu 18.04 hosts file manpage.3.     If your EC2 instance uses IPv6, add the following configuration data.::1 ip6-localhost ip6-loopback  fe00::0 ip6-localnet  ff00::0 ip6-mcastprefix  ff02::1 ip6-allnodes  ff02::2 ip6-allrouters  ff02::3 ip6-allhosts4.    Save and exit the vim editor.Note: After making this change, press SHIFT+:[colon] to open a new command entry box in the vim editor. Type wq, and then press Enter to save changes and exit vim. Or use SHIFT + ZZ to save and close the file.5.    Run the hostnamectl command and specify the new hostname. Replace the persistent-hostname with the new hostname.sudo hostnamectl set-hostname persistent-hostname6.     After you start or reboot the EC2 instance, run the Linux hostname command without any parameters to verify that the hostname change persisted.hostnameThe command returns the new hostname.Note: If you install any system updates that affect the /etc/hosts file, the hostname file, or the hostname utility, you must run these steps again.

Question: Why did I receive a bill after I closed my AWS account?

I closed my AWS account, but I received another bill. Why did I get another bill from AWS?ResolutionWhen you close your AWS account, you must terminate all your resources or you might continue to incur charges. The on-demand billing for your resources stops when you close your account.However, you might receive a bill after you close your account due to one of the following reasons:You incurred charges in the month before you closed your account: You receive a final bill for the usage incurred between the beginning of the month and the date that you closed your account. For example, if you closed your account on January 15th, then you receive a bill for usage incurred from January 1st through January 15th at the beginning of February.You have active capacity reservations on your account: You might have provisioned Amazon Elastic Compute Cloud (Amazon EC2) Reserved Instances, Amazon Relational Database Service (Amazon RDS) Reserved Instances, Amazon Redshift Reserved Instances, or Amazon ElastiCache Reserved Cache Nodes. You continue to receive a bill for these resources until the reservation period expires. For more information, see Reserved Instances.You signed up for Savings Plans: You continue to receive a bill for your compute usage covered under Savings Plans until the plan term is completed.Important: Within 90 days of closing your account, you can sign in to your account, view past billing, and pay for AWS bills.To pay your unpaid AWS bills, do the following:Open the Billing and Cost Management console.Choose Payments from the navigation pane. You can view your overdue bills in the Payments Due tab.Choose Verify and pay next to your unpaid bills to retry your payments.If the payment doesn’t have Verify and pay next to it, then contact AWS Support and ask them to retry the payment for you.

Question: Why am I getting the error "A conflicting conditional operation is currently in progress against this resource" from Amazon S3 when I try to re-create a bucket?

I deleted my Amazon Simple Storage Service (Amazon S3) bucket. Now I'm trying to create a new bucket with the same name. However, I'm getting the error: "A conflicting conditional operation is currently in progress against this resource. Try again." How can I resolve this?ResolutionAfter you send a request to delete a bucket, Amazon S3 queues the bucket name for deletion. A bucket name must be globally unique because the namespace is shared by all AWS accounts. Because Amazon S3 is a large distributed system, changes such as deleting a bucket take time to become eventually consistent across all AWS Regions.Until the bucket is completely deleted by Amazon S3, you can't use the same bucket name. However, when the bucket is deleted and the name is available, other accounts can use the bucket name. If another account uses the bucket name, you can't use the same name.Note: If you must keep a bucket name, you can empty the bucket instead of deleting it.If your application automatically creates buckets, be sure to choose a bucket-naming logic that's unlikely to cause naming conflicts. Additionally, verify that your application's logic chooses a different bucket name when a bucket name is already taken.

Question: Can I use EBS Multi-Attach volumes to enable multiple EC2 instances to simultaneously access a standard file system?

I want to access my Amazon Elastic Block Store (Amazon EBS) volume from more than one Amazon Elastic Compute Cloud (Amazon EC2) instance. Can I use Amazon EBS Multi-Attach to enable multiple EC2 instances to simultaneously access a standard file system?ResolutionStandard file systems aren't supported with EBS Multi-Attach. File systems such as XFS, EXT3, EXT4, and NTFS aren't designed to be simultaneously accessed by multiple servers or EC2 instances. Therefore, these file systems don't have built-in mechanisms to manage the coordination and control of writes, reads, locks, caches, mounts, fencing, and so on.Enabling multiple servers to simultaneously access a standard file system can result in data corruption or loss. The operation of standard file systems on EBS Multi-Attach volumes isn't a supported configuration.EBS Multi-Attach allows the attachment of a single io1 Provisioned IOPS volume to up to 16 Nitro-based instances in the same Availability Zone. EBS Multi-Attach volumes can be used as a block-level subcomponent of an overall shared storage solution. Configuration and operation of shared storage systems should be attempted only with a deep understanding of the potential pitfalls and configuration requirements. For more information on using EBS Multi-Attach, refer to Attaching a volume to multiple instances with Amazon EBS Multi-Attach - Considerations and limitations.

Question: How can I resolve high CPU utilization on my T2 or T3 EC2 Windows instance if my CPU is being throttled?

My T2 or T3 Amazon Elastic Compute Cloud (Amazon EC2) Windows instance is experiencing high CPU utilization because my CPU is being throttled. How can I fix this?ResolutionTo resolve CPU throttling, you can either enable T2/T3 Unlimited, or change the instance type.Enable T2/T3 UnlimitedThis solution has no downtime, but might cost more, especially if the instance has to burst often.Open the Amazon EC2 console, and then choose Instances from the navigation pane.Select the instance that is being throttled.For Actions, choose Instance Settings, Change T2/T3 Unlimited.Choose Enable.Note: If you still see high CPU utilization after you enable T2/T3 Unlimited, troubleshoot the process that is causing the issue. For more information, see How do I diagnose high CPU utilization on my EC2 Windows instance when my CPU is not being throttled?Change the instance typeThis solution allows you to select an instance that is better suited to your current needs if the instance has to burst often.Note: Stop your instance before you change your instance type.You can change to one of the following instance types:A T2 or T3 instance type with a higher CPU credit limit.An instance type that doesn't use a CPU credit bucket model.For more information, see How do I get more CPU and memory for my EC2 instance?Related InformationHow can I find out if the CPU on my T2 or T3 EC2 Windows instance is being throttled?
Question: "I configured Amazon CloudWatch to export log data to Amazon S3, but the log data is either missing or invalid. How do I resolve this issue?"

I configured Amazon CloudWatch to export log data to Amazon Simple Storage Service (Amazon S3) as described at Exporting log data to Amazon S3 using the AWS Command Line Interface (AWS CLI). But despite completing these steps, I can't locate any useful log file data at the specified Amazon S3 destination. What do I need to do?Short descriptionThis issue occurs because you must specify the time interval for the log data using timestamps expressed as the number of milliseconds that have elapsed since Jan 1, 1970 00:00:00 UTC.

ResolutionExport CloudWatch log data to Amazon S3 by specifying the time interval for the log data using starting and ending timestamps that are expressed in milliseconds.For example, to export CloudWatch log data to an Amazon S3 bucket or folder for the previous two-hour period, use the following syntax:aws logs create-export-task --task-name "example-task" --log-group-name "/var/logs/example-logs" --from $(($(date -d "-2 hours" +%s%N)/1000000)) --to $(($(date +%s%N)/1000000)) --destination " log_bucket" --destination-prefix "example-logs"Related informationExporting log data to Amazon S3Linux command to get time in millisecondsExporting log data to Amazon S3 using the AWS CLIExporting log data to Amazon S3 using the CloudWatch console
Question: "When I activate default encryption on my Amazon S3 bucket, do I need to update my bucket policy so that objects in the bucket are encrypted?"

I activated default encryption on my Amazon Simple Storage Service (Amazon S3) bucket. Do I need to change my bucket policy to make sure that objects stored in my bucket are encrypted?ResolutionNo, you don't need to update your bucket policy to make sure that objects stored in my bucket are encrypted. If you activate default encryption, and a user uploads an object without encryption information, then Amazon S3 uses the default encryption method that you specify. If a user specifies encryption information in the PUT request, then Amazon S3 uses the encryption specified in the request.This behavior applies to encryption with keys that are:Managed by Amazon S3.Labeled as SSE-S3 keys.Managed by AWS Key Management Service (AWS KMS).Labeled as SSE-KMS keys.For more information on encryption behavior after you activate default encryption, see Setting default server-side encryption behavior for Amazon S3 buckets.Important: After you activate default encryption using a custom AWS KMS key, you must grant users additional permissions to be able to access objects. Grant those users permissions to use the key on the key policy or on their AWS Identity and Access Management (IAM) policy. For instructions on how to grant these permissions, see My Amazon S3 bucket has default encryption using a custom AWS KMS key. How can I allow users to download from and upload to the bucket? For cross-account operations, see Using SSE-KMS encryption for cross-account operations.
