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.
