The docker CI pipeline is failing during execution of bash script-CodePudding

I am facing a problem in creating CI for docker containers. During CI build I have to remove the previous docker container and image, in this case, the build is failing when there is not any image on the server.

How can I execute this statement without stopping the build to fail?

docker rmi example/hello-world:latest

Unable to find image 'example/hello-world:latest' locally
docker: Error response from daemon:

The build is not failing in the docker stop and docker rm case:

docker stop zod || true && docker rm zod || true

How do I make sure the build doesn't fail if the image doesn't exist on the server?

This is my script for docker deployement:

docker build -t example/hello-world:latest .
docker stop zod || true && docker rm zod || true
docker rmi example/hello-world:latest
docker run --name zod -d -p 6000:6000 -dit example/hello-world:latest

CodePudding user response：

First check if the image exists, then remove it:

exists=$(docker images example/hello-world:latest | tail -n  2)
if [ -z $exists ]
then
 docker rmi example/hello-world:latest
