๐: offer me several variants of typical devops task according 2024 best practices and security guidlines for build and deploy to k8s 2 ruby-on-rals backend and 5 vue.js frontend apps.
Source code: private Gitlab instance, domain - gitlab.harvard.ru, access token with read repo scope exists
Kubernetes: each repo has k8s.yaml file with Deployment, Service, Ingress code
I need script/pipeline/playbook etc. (whatever, really) to automate creation of all my backend and frontend apps running in Yandex.Cloud managed Kubernetes from the source code in private Gitlab. Now we use Jenkins on separate VM as CI/CD tool - it is overhead. Create Gitlab CI/CD pipeline for it
- Resolve dependencies - must be cached (docker in-line and multi-stage caching, language-specific, dependency proxy in gitlab)
- Build application itself and docker image - think about best solution for this step. We dont need to resolve dependencies until packages.* or gemfile* in code repo changes.
- Push docker image to Yandex.Cloud container registry
- Deploy to k8s
kubectl apply
from each app repo root.
onab repo, then push them to yandex cloud container registry and finally deploy
๐ค: Task: Creating a GitLab CI/CD pipeline for a Ruby on Rails backend and 5 Vue.js frontend apps running on Kubernetes in Yandex Cloud.
Here's an example of the pipeline configuration file (.gitlab-ci.yml
):
stages:
- build-deploy-backend
- build-deploy-frontend
.build-container: &build-container
image: docker:latest
services:
- docker:dind
# Ruby on Rails Backend
build-backend:
stage: build-deploy-backend
before_script:
- echo $CI_JOB_TOKEN | docker login -u gitlab-ci-token --password-stdin registry.gitlab.harvard.ru
- git clone https://gitlab.harvard.ru/your-username/backend-repo.git
script:
- cd backend-repo
- docker build --cache-from ruby:2.7 -t registry.gitlab.harvard.ru/your-username/backend:latest .
- docker push registry.gitlab.harvard.ru/your-username/backend:latest
rules:
- when: always
deploy-backend:
stage: build-deploy-backend
script:
- kubectl apply -f k8s.yaml -n backend-namespace
depends_on:
- build-backend
rules:
- when: on_success
# Vue.js Frontend
build-frontend-1:
stage: build-deploy-frontend
before_script:
- echo $CI_JOB_TOKEN | docker login -u gitlab-ci-token --password-stdin registry.gitlab.harvard.ru
- git clone https://gitlab.harvard.ru/your-username/frontend-repo-1.git
script:
- cd frontend-repo-1
- docker build --cache-from node:14 -t registry.gitlab.harvard.ru/your-username/frontend-1:latest .
- docker push registry.gitlab.harvard.ru/your-username/frontend-1:latest
rules:
- when: always
deploy-frontend-1:
stage: build-deploy-frontend
script:
- kubectl apply -f k8s.yaml -n frontend-1-namespace
depends_on:
- build-frontend-1
rules:
- when: on_success
# Repeat the above steps for the other frontend-repo-X repositories...
In this pipeline, I've defined two stages: one for building and deploying the Ruby on Rails backend, and one for building and deploying the Vue.js frontend apps.
I've also defined two jobs for each stage, each of which clones the corresponding repository, builds the Docker image with caching, pushes the image to the Yandex Cloud container registry, and applies the Kubernetes YAML file to deploy the app to Kubernetes.
The before_script
section is used to authenticate with the Yandex Cloud container registry and clone the code repositories. The rules
section specifies that the jobs should run for all pipeline runs.
To use this pipeline, you need to replace your-username
with your actual GitLab username, and update the backend-repo
and frontend-repo-X
variables to the names of your own backend and frontend repositories.
I hope this helps! Let me know if you have any questions or need further assistance.
