Issue with pushing newly created image | Dagger | Page 1

My attempt to build a new image and push it to Docker hub does not seem to have any effect - all of the steps in my install script do not seem to have taken place. Can anyone tell me what is wrong? My script like so:

image: {
  pull: docker.#Pull & {
    source: "ubuntu"
  }
  install: bash.#Run & {
    input: pull.output
    script: contents: """
      apt -q update
      apt install -yqq wget    
    """
  }
  push: docker.#Push & {
    auth: {
      username: "USERNAME"
     secret: client.env.DOCKER_PASSWORD
    }
    dest: "repo/image_name:version"
    image: install.output
  }
}

👋 Hi @fast pier Do you have a full Dagger Plan? like this?

package main

import (
  "dagger.io/dagger"
  "universe.dagger.io/bash"
  "universe.dagger.io/docker"
)

dagger.#Plan & {

  client: env: DOCKER_PASSWORD: dagger.#Secret

  actions: {
    image: {
      pull: docker.#Pull & {
        source: "ubuntu"
      }
      install: bash.#Run & {
        input: pull.output
        script: contents: """
            apt -q update
            apt install -yqq wget    
          """
      }
      push: docker.#Push & {
        auth: {
          username: "jeremyatdockerhub"
          secret:   client.env.DOCKER_PASSWORD
        }
        dest:  "jeremyatdockerhub/ubuntu_test:latest"
        image: install.output
      }
    }
  }
}

worked for me

#

Yes, I have a complete plan

#

It does push, the issue is that if I reference that image in subsequent steps, it does not contain any of the changes I made to it

#

I believe the answer is I need to do a "forcePull" when I reference that image in a subsequent step

#

Alternatively, what I really want to do is commit an image locally, that I can reference in other steps

Ah, okay. So the pushed image does contain your changes, but you're having issues using that image in subsequent action steps. Let me try:

jpkbst ➤ docker run -it --rm ubuntu wget
docker: Error response from daemon: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: exec: "wget": executable file not found in $PATH: unknown.
jpkbst ➤ docker run -it --rm jeremyatdockerhub/ubuntu_test:latest wget
wget: missing URL
Usage: wget [OPTION]... [URL]...

Try `wget --help' for more options.

#

how's this?

package main

import (
  "dagger.io/dagger"
  "universe.dagger.io/bash"
  "universe.dagger.io/docker"
)

dagger.#Plan & {

  client: env: DOCKER_PASSWORD: dagger.#Secret

  actions: {
    image: {
      pull: docker.#Pull & {
        source: "ubuntu"
      }
      install: bash.#Run & {
        input: pull.output
        script: contents: """
            apt -q update
            apt install -yqq wget    
          """
      }
      push: docker.#Push & {
        auth: {
          username: "jeremyatdockerhub"
          secret:   client.env.DOCKER_PASSWORD
        }
        dest:  "jeremyatdockerhub/ubuntu_test:latest"
        image: install.output
      }
    }
    test: docker.#Run & {
      input: image.install.output
      command: {
        name: "wget"
        args: ["--version"]
      }
      always: true
    }
  }
}

#

image action has subactions of install and push.
test action uses the image created in image.install

#

dagger do test --log-format plain
