Getting ready for dev

You can develop the app on your computer. Vagrant watch the changes in the dev/synced_folder and notify nodemon to restart the modified app.

Clone the mangal-vagrant and apps repo and install dependencies

git clone --recursive git@github.com:mangal-wg/mangal-vagrant.git
# If you haven't set your own SSH key
git clone --recursive https://github.com/mangal-wg/mangal-vagrant.git
cd mangal-vagrant/dev

Don't forget to install the npm dependencies:

cd mangal-vagrant/dev/synced_folder
npm install ./mangal-api
npm install ./orcid-oauth2

Launch the Vm

cd mangal-vagrant/dev/
vagrant up --provision
# Ansible will ask the password to desencrypt ./vars/secret.yml
# and runs the procedure to setup the VM's environment and install dependencies
vagrant ssh # Reach the vm

Monitoring the server load with pm2

cd mangal-vagrant/dev/
vagrant ssh
# The apps are running at the location /var/mangal/ which belongs to the user: mangal
# To monitor the apps (logs, status etc.)
sudo su - mangal
ls -la
pm2 status
pm2 logs
pm2 monit

# see other pm2 command line: http://pm2.keymetrics.io/docs/usage/quick-start/#cheat-sheet
# logs from nginx at /var/log/nginx

Accessing the database

cd mangal-vagrant/dev/
vagrant ssh

## Connect to postgreSQL as postgres user
sudo su - postgres
psql -d mangal_dev

Accessing the dev console

If you want to have direct access to the logs for each apps with nodemon using tmux:

cd mangal-vagrant/dev/
vagrant ssh
mux

Deploy staging

The app will be deploy on the server directly from your computer Make sure you install ansible on your own computer and registered your public key on the server (ssh-copy-id). After that, you can run the following command lines:

cd mangal-vagrant/staging
ansible-playbook playbook.yml --user=tpoisot/sviss -i host.ini --vault-id .vault-pass --ask-sudo-pass

The host.ini contains the address of the server and .vault-pass file, the vault password used to desencrypt vars/secret.yml (sensitive informations).

This command line will install and setup on the server:

• postgresql
• pm2
• nodejs
• nginx
• services and permissions

All about the procedure is describe in staging/playbook.yml

Testing deployment

You can test the deployment script locally before sending it to the staging server.

git clone --recursive git@github.com:mangal-wg/mangal-vagrant.git
cd mangal-vagrant/staging
vagrant up --provision

Deploy prod

cd mangal-vagrant/staging
ssh-copy-id username@addrsrv
ansible-playbook playbook.yml --user=username -i host.ini --vault-id .vault-pass --ask-sudo-pass
