如何使用 Azure Pipeline 通过 SSH 在远程计算机上部署容器How to deploy a container on remote machine over ssh using Azure Pipeline

问：

我正在尝试在代理上将我的应用程序构建为容器映像，然后在部署步骤中，我正在对目标计算机执行 ssh 并运行 docker pull/run 命令以启动容器。它也成功启动，但一段时间后容器正在退出。

我的疑问是它仅在 ssh 会话中运行，一旦会话结束，容器就会关闭。

trigger:
  branches:
    include:
      - master
      - refs/tags/*
      - feature*

                export DOCKER_IMAGE="$(DOCKER_CONTAINER_REGISTRY)/$(APPLICATION_NAME):$(APP_VERSION)"
                echo "After Docker image is set to:$DOCKER_IMAGE"
                docker login -u $(azure_username) -p $(azure_password) $(DOCKER_CONTAINER_REGISTRY)
                echo "login succeeded"
                echo "Docker image is set to:$DOCKER_IMAGE"
                docker pull $DOCKER_IMAGE
                echo "docker pull completed"
                PREVIOUS_CONTAINER=$(docker ps -aq --filter "name=$APPLICATION_NAME")

                if [ ! -z "$PREVIOUS_CONTAINER" ]; then
                  docker stop "$PREVIOUS_CONTAINER" || true
                  docker rm "$PREVIOUS_CONTAINER" || true
                  echo "stopped previous container"
                fi
                echo "image downloaded, now running containers"
                docker run -d --name $(APPLICATION_NAME) -p 5000:5000 "$DOCKER_IMAGE"
            displayName: 'Deploy to Server'

容器日志如下：

如果我错过了任何东西或更好的实现方法，有什么建议吗？

谢谢
