NOTE

The relay server is now deployed on Heroku (repo located here), so the majority of the code in this repository is no longer used.

The only functionality that cannot be replicated on Heroku is the SSH tunneling, so this server is still deployed on Digital Ocean with the web facing services disabled.

The domain is now tunnel.heatseek.org.

Development, on a Mac

Initial Setup

bash dev/init.sh

Running

bash dev/run.sh
…
bash dev/stop.sh

Connecting to the Database

Examples:

• bash dev/db.sh
• bash dev/db.sh < commands.sql
• bash dev/db.sh pg_dump > dump.sql

Production, on CoreOS

Connecting

ssh -p 2222 [email protected]

Adding an SSH Key

update-ssh-keys -a <name> < key.pem

Initial Setup

Until we change the hub firmware to tunnel through a custom ssh port, we have to change the CoreOS ssh port to get out of the way. Currently we use 2222.

Ask a friend for the files to put in tunnel/secret/. Then:

bash db/init.sh
for x in db tunnel app web; do
  docker build --pull --tag=$x $x
  sudo systemctl enable $PWD/$x/$x.service
  sudo systemctl start $x
done
sudo systemctl enable $PWD/app/batch.service
sudo systemctl start batch

Rebuilding

For most modules, e.g. for web:

docker build --pull --tag web web
sudo systemctl restart web

Rebuilding the Batch Module

The batch module shares a lot of code with the app module, so they use the same docker image:

docker build --pull --tag app app
sudo systemctl restart batch

Connecting to the Database

Examples:

• bash db/connect.sh
• bash db/connect.sh < commands.sql
• bash db/connect.sh pg_dump > dump.sql

Status and Logs

systemctl status db tunnel app web batch
journalctl -ru web

Connecting to a Hub

docker exec -it tunnel ssh -p <port> localhost

Debugging Tunnel Ports

docker exec tunnel netstat -a | grep ssh
