Deploy to Google Cloud Run with Dagger

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
