DeployBot

This is a slack bot that is used for managing deployments of our docerized projects at DevClub.

Requirements

You need to have docker and docker-compose installed
The following directory structure (where id_rsa is the private key of ssh-key associated with github account)

.
├── docker-compose.yml
├── Dockerfile
├── ignore
│   └── keys
│       └── id_rsa          (ssh private key associated with github account)
│       └── gpg_private.asc (gpg private key associated with github account)
.
.
.

Initial Setup

Copy of `docker_conf` volume is available

Nothing needs to be done in this case.

No copy of `docker_conf` volume is present

Comment the read_only: true line for docker_conf volume in docker-compose.yml
Run: docker-compose up -d
ssh into the running docker container using: docker exec -it DeployBot_deploy /bin/bash
Setup docker-machine for all the child server using commands like: docker-machine -D create -d generic --generic-ip-address <vm_dns_name> --generic-ssh-key <ssh_key_path> --generic-ssh-user <user_name> --generic-ssh-port <ssh_port> --generic-engine-port <docker_daemon_port> <server_name>
Uncomment the commented line in first step
Run: docker-compose down

These steps will create a volume named docker_conf which will contain all the necessary information for our bot to deploy projects on configured servers. NOTE: You will also have to deploy ServerConfig on each server for projects deployed to be accessible.

Environment variables

Environment variables should be present in a .env file. These environment variables are required:

GPGSECRETPASS=<GPG passphrase>

Running

If initial setup has been done once, then just running docker-compose up -d will start the deploybot service. The bot will listen to incoming connections on port 7777 by default.

Sample project configuration

Each project should have a .env file for environment variables which should be encrypted using git-secret with devclubiitd user as collaborator. devclubiitd's public gpg key can be found here
Each project should have docker-compose.yml to build their projects.
Sample docker-compose.yml is given here with name sample_docker-compose.yml.

Note: Make sure that you have external reverseproxy network in your docker-compose.yml. Also, never use bind mounts in your compose file.
