comment fonctionne une variable
Published: 2024-02-01 15:53:11

aujourd'hui je viens montrés comment fonctionne une variable en PHP, c'est quoi une variable ?  
une variable c'est quelque chose qui dispose d'un nom, d'un type et qui stocke une ou plusieurs valeurs. en PHP  c'est un language d'équipage  faible et dynamique.C'est-à-dire que lorsqu'on va déclarer une variable dans notre code, on ne va pas spécifier son type dont on peut très bien mettre comme première valeur un entier, puis affecté à cela une chaine de caractère. PHP ne pourra pas nous mettre une erreur, car c'est possible.la syntaxe d'une variable.
une variable commence forcément par $ en PHP suivi du nom. pour les noms, nous ne devons pas laisser des espaces au tiret et il ne peut pas avoir des chiffres juste après le $, on peut mettre des chiffres mais pas après le caractère $ c'est impossible. vous pouvez le tester sur visual studio code, comme on l'a dit:$variable = 18, le 18 est la valeur affectée à la variable,
on va pouvoir l'afficher par exemple : écho $variable; ensuite on part sur notre programme, on l'actualise et vous verrez bien sûr la valeur de la variable.

Visual Generated Blogging
Tags: ai, writing
Published: 2024-02-01 16:21:35

I have a client, yep actual work, and they have blogs with lots of photos because they hold events, but they don't really write about it.

How can we solve that?

Invert blogging, normally we add photos and describe them, but as you know AI can describe what is going on in a photo.

What if each photo you uploaded photo creates a fragment.

> two young and old people stand by a 1900 green tractor

I suppose It's a little like alt-text idea but supercharged.

The sum of all the photos should be able to describe the blog post, then its a matter of giving a little prompted context and boom we have the full prompt, finally a proof read as the "editor" of the article and we are done here.

[The UI Concept](https://v0.dev/t/qkWL9M6KmfF)

Sounds like a fun experiment?

Kubernetes Essentials: Labels, Selectors, Environment Variables, and Annotations Demystified
Tags: kubernetes, label, selectors, annotation
Published: 2024-02-01 15:32:23

## Labels: Organizing and Identifying Kubernetes Resources

Viewing Labels
To display labels for pods, deployments, or all resources, use:

```
kubectl get po|deploy|all --show-labels
```
Adding Labels to Resources
Add labels to a pod, deployment, or node:

```
kubectl label po <pod-name> <label-key>=<label-value>
kubectl label deploy <deployment-name> <label-key>=<label-value>
kubectl label no <node-name> <label-key>=<label-value>
```
Removing Labels
Remove a label from a pod:


```
kubectl label po <pod-name> <label-key>-
```
Overwriting Labels
Overwrite a label for a pod:


```
kubectl label po <pod-name> <label-key>=<new-label-value> --overwrite
```

> Important Notes
> Duplicate keys are not allowed in labels.


## Selectors: Filtering Resources Based on Labels

Filtering Resources
Filter pods based on labels:


```
kubectl get po --selector=<label-key>=<label-value>

```
Inequality and Multiple Labels
Use inequality and multiple labels in selectors:


```
kubectl get po --selector=<label-key>!=<label-value>
kubectl get po --selector=<label-key>=<label-value>,<label-key>=<label-value>
```
Environment Variables: Configuring Pods
Creating Pods with Environment Variables
Run an nginx pod with an environment variable:


```
kubectl run nginx --image=nginx --env=app=web

```
Important Properties
`env` and `envFrom` properties are arrays.
`env` property takes name and value properties.

## Annotations: Adding Metadata to Resources

Adding Annotations to Pods
Annotate a pod with additional information:


```
kubectl annotate po <pod-name> <annotation-key>=<annotation-value>

```
Removing Annotations
Remove an annotation from a pod:


```
kubectl annotate po <pod-name> <annotation-key>-

```
Important Notes

> Duplicate keys are not allowed in annotations.

Enhance your Kubernetes resource organization with labels, leverage selectors for efficient filtering, configure environment variables for pods, and add valuable metadata using annotations.

Volumes: Persistent Storage in Kubernetes
Published: 2024-02-01 15:23:59

## Viewing Persistent Volumes (PV) and Persistent Volume Claims (PVC)

To check details about Persistent Volumes and Persistent Volume Claims, use the following commands:


```
kubectl get pv
kubectl get pvc

```
Deleting a Persistent Volume Claim (PVC)
Remove a specific Persistent Volume Claim:


```
kubectl delete pvc <pvc-name>
```
Deleting a Persistent Volume (PV)
Remove a specific Persistent Volume:


```
kubectl delete pv <pv-name>
```
Important Properties to Remember
Defining Volumes in Pod Specification:

```
##yaml

spec:
  volumes:
  - name: <volume-name>
    emptyDir: {}
```
Mounting Volumes in Container Specification:

```
##yaml

spec:
  containers:
  - name: <container-name>
    volumeMounts:
    - name: <volume-name>
      mountPath: <path-in-container>
```
HostPath Volume:

```
yaml
spec:
  volumes:
  - name: <volume-name>
    hostPath:
      type: Directory
      path: <host-path>
```
Persistent Volume (PV) and Persistent Volume Claim (PVC) Relationship:
PVC remains in a pending state until bound to a PV.
StorageClassName and AccessModes must match between PV and PVC.
Storage size must be within the specified range.
Reclaim Policy for Persistent Volumes
Persistent Volumes have a reclaim policy that dictates their future when the Persistent Volume Claim is deleted:

Recycle: Data in the volume is purged.
Retain: Both data and volume are retained.
Delete: Volume is deleted.
Specifying Reclaim Policy:

```
yaml

spec:
  persistentVolumeReclaimPolicy: <policy>
```
PV and PVC Selection
PVs use labels, and PVCs use selectors for PV selection.
PVs are cluster-wide, while PVCs are namespaced.
Explore the world of Persistent Volumes and Claims to provide durable storage for your Kubernetes applications.

Ingress: Effortless External Access to Your Services
Tags: kubernetes, services, ingress, externalaccess
Published: 2024-02-01 15:16:04

Checking Ingress Details
To inspect details about Ingress resources, use the following commands:


```
kubectl get ingress
kubectl describe ingress <ingress-name>
```
Modifying Ingress Configuration
Edit the configuration of an existing Ingress resource:

```

kubectl edit ingress <ingress-name>
```
Applying Ingress Configuration
Apply the configuration defined in an Ingress YAML file:

```

kubectl apply -f <ingress.yaml>
```

## Setting Up Ingress
Setting up Ingress involves the following components, all residing in the same namespace:

> Ingress Controller (Deployment)
: Responsible for fulfilling Ingress rules.

> Node Port Ingress Service:
 Enables access to the Ingress controller from outside the cluster.

> Config Map:
 Configures various parameters for the Ingress controller.

Ingress Controller Initialization
Unlike other controllers, Ingress controllers do not start automatically. They require manual deployment. Kubernetes supports various Ingress controllers for different cloud providers, such as AWS, GCE, and nginx.

Ingress Resource Rules
The Ingress resource, defined with the type 'ingress', resides in a different namespace from the application (deployment) and the service (for accessing the deployment). The Ingress resource specifies the rules, and the Ingress controller ensures their fulfillment.


Enhance your Kubernetes cluster with Ingress, providing a seamless way to access your services from the external world.

Kubernetes Jobs: Running Tasks in Kubernetes
Tags: kubernetes, jobs, cronjob, devops
Published: 2024-02-01 15:05:01



## Creating a Job
Initiate a job that runs a specific command in a container:


```
kubectl create job busybox --image=busybox -- /bin/sh -c "echo hello; sleep 30; echo world"
```
Managing Jobs
Check the status and details of all jobs in the current namespace:


```
kubectl get jobs

```
Viewing Job Logs
Retrieve logs from a specific pod created by a job:


```
kubectl logs <pod-name>

```
Deleting a Job
Remove a job and its associated pods:


```
kubectl delete job <job-name>

```
Understanding Job Properties
Jobs have several key properties to consider:

> completions
: Number of pod completions expected.
backoffLimit: Maximum number of retries before considering a job as failed.

> parallelism
: Number of pods to run in parallel.
activeDeadlineSeconds: Maximum time for the job to run.
restartPolicy: Pod restart policy, usually set to "OnFailure" or "Never".

Important Notes

> In a job, the default value for the restart property is "Never."
> A pod created by a job must have its restartPolicy set to "OnFailure" or "Never."

## CronJobs: Scheduled Jobs
Managing CronJobs
List all CronJobs in the current namespace:


```
kubectl get cronjobs

```
Creating a CronJob
Establish a CronJob that runs on a specified schedule:


```
kubectl create cronjob busybox --image=busybox --schedule="*/1 * * * *" -- /bin/sh -c "date; echo Hello from Kubernetes cluster"
```
Specifying CronJob Properties
In a CronJob, there are three spec sections to note - one for the CronJob itself, one for the Job, and one for the Pod. Important properties include:

spec -> successfulJobHistoryLimit: Number of successful jobs to retain in history.
spec -> failedJobHistoryLimit: Number of failed jobs to retain in history.
Explore the capabilities of Kubernetes Jobs and CronJobs, enhancing your control over task execution and scheduling within your cluster.
