Deploy code-push-server with Docker

This document describes how to deploy code-push-server using Docker, the instance includes three parts

  • code-push-server part
    • Update packages use local storage by default (stored on the local machine). Using docker volume storage method, container destruction won't cause data loss unless the volume is manually deleted.
    • Uses pm2 cluster mode internally to manage processes, default process count is equal to CPU count, you can configure the deploy parameters in docker-compose.yml file according to your machine configuration.
    • docker-compose.yml only provides some application parameter settings, if you need to set other configurations, you can modify the config.js file.
  • mysql part
    • Data uses docker volume storage method, container destruction won't cause data loss unless the volume is manually deleted.
    • Applications should not use root user, for security you can create a user with relatively small permissions for code-push-server to use, only select,update,insert permissions are needed. Initializing the database requires root or a user with table creation permissions
  • redis part
    • tryLoginTimes login error count limit
    • updateCheckCache improves application performance
    • rolloutClientUniqueIdCache gray release

Install Docker

Refer to Docker's official installation guide

$ docker info should output relevant information successfully, then the installation is successful and you can proceed with the following steps

Start Swarm

$ sudo docker swarm init

Get Code

$ git clone https://github.com/lisong/code-push-server.git
$ cd code-push-server/docker

Modify Configuration File

$ vim docker-compose.yml

Replace YOU_MACHINE_IP in DOWNLOAD_URL with your machine's external IP or domain

Replace YOU_MACHINE_IP in MYSQL_HOST with your machine's internal IP

Replace YOU_MACHINE_IP in REDIS_HOST with your machine's internal IP

Modify jwt.tokenSecret

code-push-server uses JSON web token encryption method for login verification, this symmetric encryption algorithm is public, so modifying the tokenSecret value in config.js is very important.

Very important! Very important! Very important!

You can open the link https://www.grc.com/passwords.htm to get a random number of type 63 random alpha-numeric characters as the key

Deploy

$ sudo docker stack deploy -c docker-compose.yml code-push-server

If the network speed is poor, you'll need to wait patiently... go chat with your friends meanwhile ^_^

Check Progress

$ sudo docker service ls
$ sudo docker service ps code-push-server_db
$ sudo docker service ps code-push-server_redis
$ sudo docker service ps code-push-server_server

Confirm that CURRENT STATE is Running about ..., then deployment is complete

Simple API Access Verification

$ curl -I http://YOUR_CODE_PUSH_SERVER_IP:3000/

Returns 200 OK

Browser Login

Default username: admin password: 123456 Remember to change the default password If you enter the wrong password too many times in a row, you will be locked out. You need to clear the redis cache

$ redis-cli -p6388  # enter redis
> flushall
> quit

View Service Logs

$ sudo docker service logs code-push-server_server
$ sudo docker service logs code-push-server_db
$ sudo docker service logs code-push-server_redis

View Storage docker volume ls

DRIVER VOLUME NAME Description
local code-push-server_data-mysql Database storage data directory
local code-push-server_data-storage Storage package files directory
local code-push-server_data-tmp Temporary directory for calculating update package differences
local code-push-server_data-redis Redis persistent data

Remove and Exit Application

$ sudo docker stack rm code-push-server
$ sudo docker swarm leave --force
