The Compute Engine container startup agent starts a container deployed on a VM instance using Deploying Containers on VMs and Managed Instance Groups method.
The agent parses container declaration that is stored in VM instance metadata
under gce-container-declaration key and starts the container with the declared
configuration options.
The agent is bundled with Container-Optimized OS image, version 62 or higher.
Container startup agent is deployed as a Docker container and is hosted in Container Registry: gcr.io/gce-containers/konlet.
To build the agent using bazel run this command from the repository root:
zel build gce-containers-startup
Export your GCP project name to an environment variable:
port MY_PROJECT=your-project-name
To build a Docker image, copy the build binary to the 'docker' directory and invoke the docker build command:
bazel-bin/gce-containers-startup/gce-containers-startup docker/
cker build docker/ -t gcr.io/$MY_PROJECT/gce-containers-startup
To push resulting Docker image to Google Container Registry you can use gcloud command:
loud docker -- push gcr.io/$MY_PROJECT/gce-containers-startup
If you would like to install the container startup agent on your VM, copy its systemd service definition and scripts:
Copy systemd service definition konlet-startup.service into systemd services directory, e.g. /usr/lib/systemd/system.
Copy get_metadata_value script to /usr/share/google directory.
Copy konlet-startup script to /var/lib/google directory
You can also those scripts directly by a startup script,
cloud-init or rc.d scripts.
