rancher-cli
Quick commands over rancher-compose and Rancher API interface helping me in devops
Profile-based approach.
Profile is a combination of API endpoint, environment, access keys with a symbolic name. Use rancher profile [profile_name] for quick switching profiles
Every profile is stored in ~/.rancher file. CLI will search this file in a working directory and in the home one.
Compose files are separated with @[profile_name]
Install
Project is written in NodeJS, so you have to install NodeJS first.
npm -g i rancher-cli
Then create your first profile: $ rancher init
Usage in CI
I am using rancher-cli container to process deploy operations to many environments from CI side. Every project has different compose@[qa|staging|production|local].yml files in VCS. .rancher file is mounted from a CI agent container.
Commands
init
Create .rancher file in a user home directory
logs
Getting last 200 lines and follow.
rancher logs [regex] -l 200 -f
start/stop
Start or stop multiple services using regexp to match stack/service
rancher stop/start [regex]
up
If service is not created - trigger launch, otherwise upgrade command will be used.
ls
List services and stacks in environment
compose
Fallback to rancher-compose commands
ssh AWS EC2-only (not impl)
Similar to my ssh2ec2 project. Will launch ssh to EC2 instance where service container is running and then be forwarded to the container.
