Hello, I am having an issue creating a secondary TAG on a Docker Image using the new

@pulumi/docker

v4.0.0: The example below shows how to create and push a Docker Image with tag

xyz

, but how can I tag the image with a secondary TAG

latest

?

const demoImage = new docker.Image("demo-image", {
    build: {
        context: ".",
        dockerfile: "Dockerfile",
    },
    imageName: "host/image:xyz"
});

The desired result is to being able to publish both: •

host/image:latest

•

host/image:xyz

this works for me

const demoImage = new docker.Image("demo-image", {
    build: {
        context: ".",
        dockerfile: "Dockerfile",
    },
    imageName: "test/image:bar",
    skipPush: true,
});

new docker.Tag("demo-tag", {
    sourceImage: demoImage.imageName as pulumi.Output<string>, // ensure the optional type is string
    targetImage: "test/image:foo",
  });

@gentle-state-12755 Is this a multi-platform image? If so, that's why it might not work.

@billowy-army-68599 I see what is happening. you are right, locally the tag

foo

is created correctly But how to push

foo

remotely together with

bar

?

const demoImage = new docker.Image("demo-image", {
    build: {
        context: ".",
        dockerfile: "Dockerfile",
    },
    imageName: "host/image:bar",
    registry: {...},
});

new docker.Tag("demo-tag", {
    sourceImage: demoImage.imageName as pulumi.Output<string>,
    targetImage: "test/image:foo",
  });

The

bar

tag is found in the remote repository

host

, but not the

foo

tag

We might need to make tag an array,‘could you file an issue

sure thing. just to make sure I get what you are talking about: you suggest a change to support something like ?

const demoImage = new docker.Image("demo-image", {
    build: {
        context: ".",
        dockerfile: "Dockerfile",
    },
    imageName: "host/image",
    tags: [
      'foo',
      'bar'
    ],
    registry: {...},
});

Or an array for imageName

✅

it occured to me last night @gentle-state-12755 the right way is probably this

const demoImage = new docker.Image("demo-image", {
    build: {
        context: ".",
        dockerfile: "Dockerfile",
    },
    imageName: "test/image:bar",
    skipPush: true,
});

const demoImageTag = new docker.Image("demo-image-tag", {
        imageName: "test/image:foo",
        skipPush: true,
        build: {
            context: ".",
            dockerfile: "Dockerfile",
        }
})

Let the underlying docker caching do the work

yes, but I guess one should

dependOn

the other. If not, is docker going to try to build them in parallel ?

yeah that’d work
