Deploy to Google Cloud Run with Dagger

caution

This is documentation for Dagger 0.1, which is no longer actively maintained.

For up-to-date documentation, see the latest version (0.2).

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
