Run locally

# build
docker build -t hello-actix -f ./Dockerfile .

# run
docker run --rm --name hello-actix -p 8080:8080 -e "TARGET=foo" hello-actix

# view
open http://localhost:8080

Deploy directly to CloudRun via macOS

# Ensure we are all set
gcloud auth login

# See the projects list
gcloud projects list

# Your config for CloudRun
export PROJECT_ID=YOUR_PROJECT_ID_SEE_ABOVE
export PROJECT_NUMBER=YOUR_PROJECT_NUMBER_SEE_ABOVE
export SERVICE_NAME=hello-actix

gcloud config set project $PROJECT_ID

# Enable cache https://github.com/GoogleContainerTools/kaniko
gcloud config set run/platform managed
gcloud config set builds/use_kaniko True
gcloud config set builds/kaniko_cache_ttl 24

# Give serviceAccount build permissions
gcloud projects add-iam-policy-binding $PROJECT_ID \
    --member="serviceAccount:service-$PROJECT_NUMBER@gcp-sa-cloudbuild.iam.gserviceaccount.com" \
    --role="roles/cloudbuild.serviceAgent"

# Submit build
gcloud builds submit --tag gcr.io/$PROJECT_ID/$SERVICE_NAME --timeout=30m

# Deploy with environment variables
gcloud run deploy --image gcr.io/$PROJECT_ID/$SERVICE_NAME --set-env-vars TARGET=foo

# Update environment variables (optional for testing)
gcloud run services update $SERVICE_NAME --update-env-vars TARGET=bar

A trap (2024)

see Granting a role to the Cloud Build service agent

ERROR: (gcloud.builds.submit) FAILED_PRECONDITION: invalid bucket "123.cloudbuild-logs.googleusercontent.com"; service account 123-compute@developer.gserviceaccount.com does not have access to the bucket

Solution

gcloud projects add-iam-policy-binding $PROJECT_ID \
    --member="serviceAccount:service-$PROJECT_NUMBER@gcp-sa-cloudbuild.iam.gserviceaccount.com" \
    --role="roles/cloudbuild.serviceAgent"
