应用错误收集

我有一个要通过GitLab CI进行部署的Dockerized Angular / Node.js应用程序。

我使用GitLab CI，使用带有Runner的专用构建VM /服务器来构建映像并将其推送到GitLab容器注册表，然后应在其他服务器（即生产服务器）中将图像作为容器拉出并启动。

这是我的gitlab-ci.yml文件现在的样子：

image: docker:latest

#services:
#    - docker:dind

stages:
    - build
    - deploy

build-1:
    stage: build
    only:
        - deploy
    script:
        - docker login -u $GITLAB_USERNAME -p $CI_ACCESS_TOKEN $CI_REGISTRY
        - docker build -t $FRONTEND_IMG .
        - echo Pushing Docker image to GitLab
        - docker push $FRONTEND_IMG
    when: manual
    tags:
        - my-runner

build-2:
  stage: build
  only:
    - deploy
  script:
    - docker login -u $GITLAB_USERNAME -p $CI_ACCESS_TOKEN $CI_REGISTRY
    - docker build -t $BACKEND_IMG .
    - docker push $BACKEND_IMG
  when: manual
  tags:
    - my-runner

deploy-live:
    stage: deploy
    only:
        - deploy
    before_script:
        ## Install ssh-agent if not already installed, it is required by Docker.
        ## (change apt-get to yum if you use an RPM-based image)
        ##
        - 'which ssh-agent || ( apt-get update -y && apt-get install openssh-client -y )'

        ##
        ## Run ssh-agent (inside the build environment)
        ##
        - eval $(ssh-agent -s)

        ##
        ## Add the SSH key stored in SSH_PRIVATE_KEY variable to the agent store
        ## We're using tr to fix line endings which makes ed25519 keys work

        ## https://gitlab.com/gitlab-examples/ssh-private-key/issues/1#note_48526556
        ##
        - echo "$SSH_PRIVATE_KEY" | tr -d '\r' | ssh-add -

        ##
        ## Create the SSH directory and give it the right permissions
        ##
        - mkdir -p ~/.ssh
        - chmod 700 ~/.ssh

        # - mkdir -p ~/.ssh && touch ~/.ssh/known_hosts
        # - echo "$SSH_KNOWN_HOSTS" >> ~/.ssh/known_hosts
        ##
        ## Use ssh-keyscan to scan the keys of your private server. Replace gitlab.com
        ## with your own domain name. You can copy and repeat that command if you have
        ## more than one server to connect to.
        ##
        - ssh-keyscan $SERVER_IP_ADDRESS >> ~/.ssh/known_hosts
        - chmod 644 ~/.ssh/known_hosts
    script:
        - echo SSH to prod server
        - ssh $SERVER_USERNAME@$SERVER_IP_ADDRESS && ip addr show && docker login -u $GITLAB_USERNAME -p $CI_ACCESS_TOKEN $CI_REGISTRY && docker pull $FRONTEND_IMG && docker pull $BACKEND_IMG && docker-compose -f docker-compose.yml up -d
    when: manual
    tags:
        - my-runner

问题是，docker命令似乎在构建服务器上执行（而不是在我们的ssh生产服务器上），并且可以从那里访问应用程序，但不能从生产服务器上访问该应用程序。
在部署后在生产服务器上运行docker images时，该列表显示为空。但是，当我在构建服务器中执行此操作时，已构建的图像就在其中。
该作业似乎成功完成，没有任何错误消息，但我确实收到了以下消息：

Pseudo-terminal will not be allocated because stdin is not a terminal.

我想念什么或做错什么了？

在查看您的 ci 代码后，当您想在生产服务器上运行容器时，您应该使用 ansible。

Ansible 优于

ssh myserver "command1 && command2 &&....."

我可以与您分享我的 ansible 文件 deploy.yml

终于hosts

127.0.0.1 env=prod

[remote]
xxx.xxx.xxx ansible_user=root env=prod

像 fei yang 一样，我也建议将 ssh 命令替换为 ansible。

我认为可能存在这个问题：

ssh $SERVER_USERNAME@$SERVER_IP_ADDRESS && ip addr show

在我的电脑上我可以运行：

curl ipinfo.io

并得到：

{
  "ip": "193.118.225.242"
...

然后我输入：

ssh root@104.248.40.145 && curl ipinfo.io

我明白了：

Last login: Thu Jun 17 07:53:38 2021 from 193.118.225.242

我已登录到服务器，但看不到 ipinfo

的结果

当我打字时

exit

从远程服务器注销我可以看到：

logout
Connection to 104.248.40.145 closed.
{
  "ip": "193.118.225.242",

要通过 ssh 远程执行命令，您不应使用 && 而应使用 "" 例如。

ssh root@104.248.40.145 "curl ipinfo.io"

使用Gitlab CI进行构建和部署？
