条件docker命令-找不到docker

Question

我试图在部署时实现以下目标：

• [如果找到旧容器]重命名并停止
• 从最新映像运行新容器

我用这种方式尝试(这是我的gitlab ci.yml的代码(

# these two work, so docker is running and reachable
- ssh deploy@$URL_STAGE docker login -u $CI_REGISTRY_USER -p $CI_JOB_TOKEN $CI_REGISTRY
- ssh deploy@$URL_STAGE docker pull $CI_REGISTRY_IMAGE/$AMC_BACKEND_DOCKER_IMAGE_NAME:latest
# rename and stop ('docker inspect' to ensure the container exists, see https://stackoverflow.com/a/45171589)
- ssh deploy@$URL_STAGE docker container inspect $AMC_BACKEND_DOCKER_IMAGE_NAME     > /dev/null 2>&1   && docker rename $AMC_BACKEND_DOCKER_IMAGE_NAME $AMC_BACKEND_DOCKER_IMAGE_NAME-bkp
- ssh deploy@$URL_STAGE docker container inspect $AMC_BACKEND_DOCKER_IMAGE_NAME-bkp > /dev/null 2>&1   && docker stop -t 5 $AMC_BACKEND_DOCKER_IMAGE_NAME-bkp  # sends SIGTERM and after t seconds SIGKILL

日志的最后几行是

$ ssh deploy@$URL_STAGE docker pull $CI_REGISTRY_IMAGE/$AMC_BACKEND_DOCKER_IMAGE_NAME:latest
...
Status: Downloaded newer image for ...:latest
$ ssh deploy@$URL_STAGE docker container inspect $AMC_BACKEND_DOCKER_IMAGE_NAME     > /dev/null 2>&1   && docker rename $AMC_BACKEND_DOCKER_IMAGE_NAME $AMC_BACKEND_DOCKER_IMAGE_NAME-bkp
/bin/sh: eval: line 155: docker: not found

• 我将相同的命令复制到服务器(替换变量(，它在那里工作
• 也适用于ssh localhost docker ...
• 删除> /dev/null 2>&1时也不起作用

不知何故，&amp；似乎在运行"；其他地方"；(在不存在命令docker的情况下(

知道吗？

我现在这样做(使用多行命令只连接一次(

ssh deploy@$URL_STAGE "
# -x Makes the server print the executed commands to stdout. 
# -e Makes the execution stop when one of the commands fails.
set -x -e
### keep the last two containers for easy roleback ###
# if there is a bkp2 container -> remove it
docker container inspect $AMC_BACKEND_DOCKER_IMAGE_NAME-bkp2 > /dev/null 2>&1   && docker rm $AMC_BACKEND_DOCKER_IMAGE_NAME-bkp2

# if there is a bkp container -> rename it to bkp2
docker container inspect $AMC_BACKEND_DOCKER_IMAGE_NAME-bkp  > /dev/null 2>&1   && docker rename $AMC_BACKEND_DOCKER_IMAGE_NAME-bkp $AMC_BACKEND_DOCKER_IMAGE_NAME-bkp2        
# if there is a former app container -> stop it and rename it to bkp
docker container inspect $AMC_BACKEND_DOCKER_IMAGE_NAME      > /dev/null 2>&1   && docker stop -t 5 $AMC_BACKEND_DOCKER_IMAGE_NAME
