3.2.2 Uploading your container

Now it’s time to upload your container to a container registry.

Create a new repo

Go to https://console.cloud.google.com/artifacts and create a new repository of type Docker in your desired location.

Use the UI to copy the path that is generated, which will look something like us-west1-docker.pkg.dev/gke-autopilot-test/timeserver.

Authenticate

Cloud Shell is configured automatically. On other environments, take the host from that path, and use it here to authenticate docker:

HOST_NAME=us-west1-docker.pkg.dev
gcloud auth configure-docker $HOST_NAME

Tag

Append the image name and version timeserver:1 to the repository path. For example for the path us-west1-docker.pkg.dev/gke-autopilot-test/timeserver you would use us-west1-docker.pkg.dev/gke-autopilot-test/timeserver/timeserver:1

You can tag an existig image, like so (where timeserver was the previous tag).

IMAGE_TAG=us-west1-docker.pkg.dev/gke-autopilot-test/timeserver/timeserver:1
docker tag timeserver $IMAGE_TAG

List your local images to find those tags

$ docker images
REPOSITORY   TAG       IMAGE ID       CREATED         SIZE
timeserver   latest    7f15ce6d0d5b   4 seconds ago   1.02GB

No existing image? No problem. Build and tag at the same time:

IMAGE_TAG=us-west1-docker.pkg.dev/gke-autopilot-test/timeserver/timeserver:1
cd Chapter02/timeserver
docker build . -t $IMAGE_TAG

Push

Once authenticated and tagged correctly, you can push the image

$ docker push $IMAGE_TAG
The push refers to repository [us-west1-docker.pkg.dev/gke-autopilot-test/timeserver/timeserver]

The image should now be in Artifact Registry
