Build images without pushing

In Harness CI, you can build images without pushing them. For example, you can use your CI pipeline to test a Dockerfile from your codebase to verify that the resulting image is correct before you push it to your Docker repository.

The configuration depends on your build infrastructure:

Harness Cloud, local runner, or self-managed VM​

To build without pushing on Harness Cloud, a local runner, or a self-managed VM build infrastructure, add the following environment variable to your Build and Push step:

                    envVariables:
                      PLUGIN_DRY_RUN: true

Kubernetes cluster running as root​

To build without pushing on a Kubernetes cluster build infrastructure running as root, add the following environment variable to your Build and Push step:

                    envVariables:
                      PLUGIN_NO_PUSH: true

Kubernetes cluster running as non-root​

To build without pushing with the Buildah plugin, which is used to build and push with non-root users, add the following stage variable to the stage where you use the Buildah plugin:

        variables:
          - name: PLUGIN_DRY_RUN
            type: String
            description: ""
            required: false
            value: "true"
