创建react应用+ Gitlab CI + Digital Ocean Drop-管道成功,但之后立即删除Docker容器

我正在迈入Docker / CI / CD的第一步。

为此,我正在尝试使用Gitlab CI将原始create-react-app部署到我的Digital Ocean Droplet(Docker一键式应用程序)。这些是我的文件:

Dockerfile.yml

# STAGE 1 - Building assets
FROM node:alpine as building_assets_stage
WORKDIR /workspace

## Preparing the image (installing dependencies and building static files)
COPY ./package.json .
RUN yarn install
COPY . .
RUN yarn build

# STAGE 2 - Serving static content
FROM nginx as serving_static_content_stage
ENV NGINX_STATIC_FILE_SERVING_PATH=/usr/share/nginx/html
EXPOSE 80
COPY --from=building_assets_stage /workspace/build ${NGINX_STATIC_FILE_SERVING_PATH}

docker-compose.yml

## Use a Docker image with "docker-compose" installed on top of it.
image: tmaier/docker-compose:latest
services:
  - docker:dind

variables:
  DOCKER_CONTAINER_NAME: ${CI_PROJECT_NAME}
  DOCKER_IMAGE_TAG: ${SECRETS_DOCKER_LOGIN_USERNAME}/${CI_PROJECT_NAME}:latest

before_script:
  ## Install ssh agent (so we can access the Digital Ocean Droplet) and run it.
  - apk update && apk add openssh-client
  - eval $(ssh-agent -s)

  ## Write the environment variable value to the agent store, create the ssh directory and give the right permissions to it.
  - echo "$SECRETS_DIGITAL_OCEAN_DROPLET_SSH_KEY" | ssh-add -
  - mkdir -p ~/.ssh
  - chmod 700 ~/.ssh

  ## Make sure that ssh will trust the new host, instead of asking
  - echo -e "Host *\n\tStrictHostKeyChecking no\n\n" > ~/.ssh/config

  ## Test that everything is setup correctly
  - ssh -T ${SECRETS_DIGITAL_OCEAN_DROPLET_USER}@${SECRETS_DIGITAL_OCEAN_DROPLET_IP}

stages:
  - deploy

deploy:
  stage: deploy
  script:
    ## Login this machine into Docker registry, creates a production build and push it to the registry.
    - docker login -u ${SECRETS_DOCKER_LOGIN_USERNAME} -p ${SECRETS_DOCKER_LOGIN_PASSWORD}
    - docker build -t ${DOCKER_IMAGE_TAG} .
    - docker push ${DOCKER_IMAGE_TAG}

    ## Connect to the Digital Ocean droplet, stop/remove all running containers, pull latest image and execute it.
    - ssh -T ${SECRETS_DIGITAL_OCEAN_DROPLET_USER}@${SECRETS_DIGITAL_OCEAN_DROPLET_IP}
    - docker ps -q --filter "name=${DOCKER_CONTAINER_NAME}" | grep -q . && docker stop ${DOCKER_CONTAINER_NAME} && docker rm -fv ${DOCKER_CONTAINER_NAME} && docker rmi -f ${DOCKER_IMAGE_TAG}
    - docker run -d -p 80:80 --name ${DOCKER_CONTAINER_NAME} ${DOCKER_IMAGE_TAG}

    # Everything works, exit.
    - exit 0
  only:
    - master

简而言之,在Gitlab CI上,我执行以下操作:

  1. (before_install)安装ssh代理并将我的私有SSH密钥复制到此计算机上,以便我们可以连接到Digital Ocean Droplet;

  2. (部署),我构建映像并将其推送到我的公共docker hub存储库中;

  3. (部署),我通过SSH连接到我的Digital Ocean Droplet,提取刚刚构建的映像并运行它。

问题是,如果我从计算机的终端执行所有操作,则会创建容器并成功部署应用程序。

如果我从Gitlab CI任务执行,则会生成容器,但不会部署任何内容,因为容器在(click here to see CI job output)之后就死了。

我可以保证容器将被擦除,因为如果我手动对服务器和docker ps -a进行SSH加密,则它不会监听任何内容。

我对此映像CMD为CMD ["nginx", "-g", "daemon off;"]感到困惑,这不应该使我的容器因为正在运行的进程而被删除。

我做错了什么?我迷路了。

谢谢。

d g回答了我的问题-非常感谢!

问题取决于以下事实:我应该通过SSH将其连接到Digital Ocean Droplet并在其bash中执行命令时将整个命令作为参数传递给ssh指示。

将我的.gitlab.yml文件从以下位置更改:

    ## Connect to the Digital Ocean droplet, stop/remove all running containers, pull latest image and execute it.
    - ssh -T ${SECRETS_DIGITAL_OCEAN_DROPLET_USER}@${SECRETS_DIGITAL_OCEAN_DROPLET_IP}
    - docker ps -q --filter "name=${DOCKER_CONTAINER_NAME}" | grep -q . && docker stop ${DOCKER_CONTAINER_NAME} && docker rm -fv ${DOCKER_CONTAINER_NAME} && docker rmi -f ${DOCKER_IMAGE_TAG}
    - docker run -d -p 80:80 --name ${DOCKER_CONTAINER_NAME} ${DOCKER_IMAGE_TAG}

收件人:

# Execute as follow:
# ssh -t digital-ocean-server "docker cmd1; docker cmd2;
- ssh -T ${SECRETS_DIGITAL_OCEAN_DROPLET_USER}@${SECRETS_DIGITAL_OCEAN_DROPLET_IP} "docker ps -q --filter \"name=${DOCKER_CONTAINER_NAME}\" | grep -q . && docker stop ${DOCKER_CONTAINER_NAME} && docker rm -fv ${DOCKER_CONTAINER_NAME} && docker rmi -f ${DOCKER_IMAGE_TAG}; docker run -d -p 80:80 --name ${DOCKER_CONTAINER_NAME} ${DOCKER_IMAGE_TAG}"
