Instances – AWS CLI

  1. aws ec2 describe-instances | jq -cr ‘.Reservations[].Instances[0]|[.InstanceId,.InstanceType,.KeyName,.State,.Tags]’ # list instances
  2. aws ec2 describe-instance-status –instance-id <INST-ID> | jq ‘ .InstanceStatuses | .[].InstanceState.Name’ # show instance
  3. aws ec2 start-instances –instance-id <INST-ID> # start instance

LoadBalancers – AWS CLI

  2. aws elbv2 describe-listeners –load-balancer-arn <ARN>  | jq -c ‘.|.Listeners[]|[.Protocol,.Port,.ListenerArn] # list listeners

Git clone – gitlab docker

HowTo: clone from a gitlab server running inside a docker container

  1. Ensure SSH pubkey is setup by following https://docs.gitlab.com/ee/ssh/
  2. Check source port for SSH here:

docker inspect gitlab | jq '.[0].NetworkSettings.Ports."22/tcp"'

  1. This .ssh/config worked for me

Host git
Hostname 127.0.0.1
User git
Identityfile ~/.ssh/id_ed25519
Port 922

  1. Then clone like this:

git clone git@git:root/my-awesome-project.git
