Deploy to Google Cloud Run with Dagger

caution

This documentation is for an older version of Dagger, which is no longer actively maintained.

We encourage you to upgrade and refer to the documentation for the most current version.

If you cannot upgrade to the latest version, please contact us in the help forum on Discord. When contacting us, please let us know why you cannot move to the latest version. From there, our team will work with you on your use case.

This tutorial illustrates how to use Dagger to build, push and deploy Docker images to Cloud Run.

Initialize a Dagger Project and Environment​

(optional) Setup example app​

You will need the local copy of the Dagger examples repository used in previous guides

git clone https://github.com/dagger/examples

Make sure that all commands are being run from the todoapp directory:

cd examples/todoapp

Organize your package​

Let's create a new directory for our Cue package:

mkdir gcpcloudrun

Create a basic plan​

todoapp/gcpcloudrun/source.cue
package gcpcloudrun

import (
    "alpha.dagger.io/dagger"
    "alpha.dagger.io/docker"
    "alpha.dagger.io/gcp"
    "alpha.dagger.io/gcp/cloudrun"
    "alpha.dagger.io/gcp/gcr"
)

// Source code of the sample application
src: dagger.#Artifact & dagger.#Input

// GCR full image name
imageRef: string & dagger.#Input

image: docker.#Build & {
    source: src
}

gcpConfig: gcp.#Config

creds: gcr.#Credentials & {
    config: gcpConfig
}

push: docker.#Push & {
    target: imageRef
    source: image
    auth: {
        username: creds.username
        secret:   creds.secret
    }
}

deploy: cloudrun.#Service & {
    config: gcpConfig
    image:  push.ref
}

Set up the environment​

Create a new environment​

Let's create a project:

dagger init

Let's create an environment to run it:

dagger new 'gcpcloudrun' -p ./gcpcloudrun

Configure user inputs​

dagger input dir src . -e gcpcloudrun
dagger input text deploy.name todoapp -e gcpcloudrun
dagger input text imageRef gcr.io/<your-project>/todoapp -e gcpcloudrun
dagger input text gcpConfig.region us-west2 -e gcpcloudrun
dagger input text gcpConfig.project <your-project> -e gcpcloudrun
dagger input secret gcpConfig.serviceKey -f ./gcp-sa-key.json -e gcpcloudrun

Deploy​

Now that everything is set correctly, let's deploy on Cloud Run:

dagger up -e gcpcloudrun
