Hi All,

Hope everyone are doing fine.

We are migrating from bamboo to Jenkins and finding some hurdles during
this process.

We are trying to create agent which uses docker image and start building
our job inside the container. PFB code snippet we used

agent {
    docker {
        image 'maven:3.8.1-adoptopenjdk-11'
    }
}

In the above scenario we faced "docker command not found" error and changed
to below snippet.

agent {
    docker {
        image 'myregistry.com/node'
        registryUrl 'https://myregistry.com/'
        registryCredentialsId 'myPredefinedCredentialsInJenkins'
    }
}

While when the above snippet is executed we are getting below error.

Note: We do have very limited access in Jenkins, so most of our work will
involve trying around in pipeline script.

Looking for solution.Please do let us know on what we are missing.

Regards,
Sushma
