[devops] cicd設定 (gitlab-ci.yml說明)

利用GIT LAB做CICD自動部屬

.gitlab-ci.yml 說明

下表中表示 git會交給runner做三件事:
build → deploy

stages:
- build
- deploy

- build

docker-build-dev:   #操作名稱
 stage: build       #對應到上面的階段
 image: docker:latest #因使用docker做自動部屬 所以指定docker image
 tags:
 - pathOnly         #指定由哪個RUNNER做操作
 services:
 - docker:dind
script:            #啟動docker 進入環境後須執行的command
 - docker login -u $REPOSITORY_ACCOUNT -p $REPOSITORY_PASSWORD $REPOSITORY_URL
 - docker build -t $IMAGE_NAME_DEV .
 - docker push $IMAGE_NAME_DEV
 only:              # 只有在某個分支 被更新時啟動
 - develop

- deploy

deploy_dev:
stage: deploy
image: kroniak/ssh-client
tags:
- pathOnly
before_script:
- mkdir -p ~/.ssh
- chmod 700 ~/.ssh
- echo -e "Host *\n\tStrictHostKeyChecking no\n\n" > ~/.ssh/config
- echo "$DEV_SSH_PRIVATE_KEY" > ~/.ssh/id_rsa
- chmod 600 ~/.ssh/id_rsa
script:
- ssh $DEV_SSH_HOST "docker rm -f $DEV_PROJECT_NAME" || true
- ssh $DEV_SSH_HOST "docker login -u $REPOSITORY_ACCOUNT -p $REPOSITORY_PASSWORD $REPOSITORY_URL"
- ssh $DEV_SSH_HOST "docker pull $IMAGE_NAME_DEV"
- ssh $DEV_SSH_HOST "docker run ********"
only:
- develop
