在gitlab跑步者完成構建之後部署

Question

我想要使用gitlab跑步者部署成功構建的docker鏡像，但我不確定如何使用.gitlab-ci.yml中的部署階段來執行此操作。構建日誌顯示在構建過程中數據庫在Docker鏡像上正確創建。

我在Mac上本地使用docker（OSX 10.11.6）來構建我的docker容器。 Gitlab正在遠程運行。我註冊了一個特定的本地運動員來處理構建。當我將更改推送到我的項目時，gitlab CI將運行構建腳本來創建測試數據庫。圖像生成後會發生什麼？在本地機器上列出的已完成的版本沒有碼頭圖像。 gitlab-runner-prebuilt-x86_64是一個準系統的linux映像，與構建不相關。

您不在CI上構建任何泊塢窗圖像。

您正在使用DockerHub的php7圖像執行所有作業。這包括正在嘗試使用docker二進制推送不在該容器內的圖像（deploy:latest）的作業deploy_job1。另外，我認爲docker二進制文件不包含在php7圖片上。

我猜你想要在Mac上本地生成的圖像，不是嗎？在這種情況下，你需要使用另一個亞軍，其執行者應該是shell。在這種情況下，您將有2名參賽者，一名使用docker運行build_job1作業，另一名參賽者推送本地構建的圖像。但是有一個更好的解決方案可以手動構建Docker鏡像，並且可以讓GitLab CI構建它。

所以，對矯正你的.gitlab-ci.yml（刪除你的意見，並補充地雷解釋）：

# Removed global image definition 

stages: 
    - build 
    - test 
    - deploy  

variables: 
    db_name: db_test 
    db_schema: "db_test_schema.sql" 

build_job1: 
    stage: build 
    # Use image ONLY in docker runner 
    image: php7:latest 
    script: 
    - service mysql start 
    - echo "create database $db_name" | mysql -u root 
    - mysql -u root $db_name < $db_schema 
    - mysql -u root -e "show databases; use $db_name; show tables;" 
    # Run on runner with docker executor, this is ok 
    tags: 
    - docker 

deploy_job1: 
    stage: deploy 
    script: 
    # Build the docker image first, and then push it 
    - docker build -t deploy:latest . 
    - docker push deploy:latest 
    # Run on runner with shell executor, set proper tag 
    tags: 
    - docker_builder 

當您註冊新轉輪，設置執行爲shell和標籤docker_builder。我假裝你已經在你的Mac上安裝了docker引擎。

另一方面，這個例子是沒有意義的，至少對我而言。由於容器是短暫的，因此build階段什麼也不做。我想你應該在Dockerfile上做到這一點。
