Goal:

We are going to create new git repository and configure your server (Droplet) to run Parse Server.

Expected result:

Your repository will contain server configuration. Server environment (pythons packages, docker containers) will be deployed on your Droplet. Parse Server, Mongo and Dashboard will be working on server.

Step 1. Server configuration

  • Create DO droplet (Ubuntu 16.04 x64), launch it, and get ip

DevOps things:

  • You need to prepare client certificate, please read Prepare chains of certs
  • Prepare DNS name in your DNS account with ip from previous step

Step 2. Script configuration

Script is a thing that will deploy everything on server.

2.1 Generate configuration files (Init setup)

  • Run first script, you need prepared staging password and folder with client's ssl
./scripts/init-new-project.sh
  • Add your remote origin url to parse server project
git remote add origin ssh://git@github.com:your-project.git

Important: save all generated keys into your project's wiki! They are important!

  • Edit inventories files, set ip for server
nano inventories/staging
nano inventories/production
  • Edit common config
nano group_vars/all.yml
  • Edit staging/production config
nano group_vars/staging.yml
nano group_vars/production.yml

  • Edit newrelic.js in the root folder with correct app_name

  • Edit package.json in the root folder with correct npm versions

  • Commit and push to remote git

2.2 Run Script

  • Run ansible init script for setup staging/production
# for staging
ansible-playbook -i inventories/staging init.yml --ask-vault-pass --extra-vars "ansible_port=22 drop_database=true"
# for production
ansible-playbook -i inventories/production init.yml --ask-vault-pass --extra-vars "ansible_port=22 drop_database=true"

Where:

  • -i inventories/production.yml use specific inventory file with ip
  • --ask-vault-pass use for staging/production password asking
  • --extra-vars "ansible_port=22" use env ansible_port=22
  • drop_database=true will drop whole MongoDb; it's required if you want to migrate database from Parse.

This script will use your configuration files and setup everything on server.

Troubleshooting

I see scary 'you're under MitM attack' message.

Smth like this: "WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY! Someone could be eavesdropping on you right now (man-in-the-middle attack)!".
No worries. Server's ssh key was changed. All you need to do is to remove server's ip from known_hosts file.

open ~/.ssh/known_hosts

and remove server's ip (probably the last row).

What's next?

  • migrate MongoDB
  • make sure that server's code is working
  • setup monitoring
