Google Compute Engine CLI

gcloud command

Activate service account

gcloud auth activate-service-account --key-file=key.json

List and select projects

When managing more then one project, you can list and select projects with:

$ gcloud projects list
PROJECT_ID           NAME                 PROJECT_NUMBER
compute-engine-6969  jsosic-foobar1       429052673518
compute-engine-6970  jsosic-foobar2       249042524163

gcloud config set project compute-engine-6969

Start and stop instances

gcloud compute instances --project <projectname> start <instance1> <instance2>

Serial console

Physical servers usually have some kind of remote console, like KVM, iLO, iDRAC ... Google offers Virtual Serial Console, which is currently still in beta. It is not as powerfull as iDRAC and relatives, but it does help.

To access it, you need to enable it first:

gcloud compute instances add-metadata [INSTANCE_NAME] --metadata=serial-port-enable=1

Now, create files:

~/.ssh/google_compute_engine
~/.ssh/google_compute_engine.pub

These files represent keys that are set in project metadata for an user present over there.

Afterwards you can connect to it by running:

gcloud beta compute connect-to-serial-port [USER]@[INSTANCE_NAME]

To disconnect from the serial console:

Press the ENTER key.
Type ~. (tilde, followed by a period).

Log in docker to registry

Download keyfile and use it to log in:

docker login -u _json_key -p "$(cat keyfile.json)" https://gcr.io
