docker: command not found when use agent image with "-podman" suffix

[usernameisnull]

when use "-podman" agent image, in jenkins pipeline, if I use sh 'docker ...' ,it said: docker: command not found I think this stamement is not work https://github.com/kubesphere/devops-agent/blob/d7797562cce10d844ab146fc8c6be39024d94f18/base/podman/Dockerfile#L62

Could you please tell us the exactly image name and tag?

Could you please tell us the exactly image name and tag? builder-base:v3.2.0-podman,but I think any agent image with "-podman" suffix will have this problem

In jenkins pipeline, if I use docker in sh statements，this will happen，so I changed the docker to podman

stage('build & push') {
      steps {
        container('base') {
          withCredentials([usernamePassword(credentialsId: 'harbor-credential', passwordVariable: 'PASS', usernameVariable: 'USER',)]) {
            sh '''
             export IMG="myregistry.com/demo/hello:$IMAGE_TAG"
             podman login myregistry.com/demo -u $USER -p $PASS
             podman build -f Dockerfile.with-build -t \$IMG  .
             podman push \$IMG
          '''
          }
        }
      }
    }

if use docker:

it was fixed in https://github.com/kubesphere/devops-agent/pull/68. You could use ghcr.io/kubesphere/builder-base:v3.2.2-podman instead.

See also:

[root@node1 ~]# docker run ghcr.io/kubesphere/builder-base:v3.2.2-podman docker
Error: missing command 'docker COMMAND'
Try 'docker --help' for more information.

nice

there is another problem: I found that your other 3.2.2-podman images still have this problem，like：kubespheredev/builder-maven:v3.2.2-podman you still use alias not ln -s

[LinuxSuRen]

The alias does not work well in kubespheredev/builder-maven:v3.2.2-podman due to the following file

https://github.com/kubesphere/devops-agent/blob/d7797562cce10d844ab146fc8c6be39024d94f18/maven/podman/Dockerfile#L1

I think we should upgrade the base image. Please feel free to do it if you're interested in it.
