Setting up an admin server

Set up an appropriate instance. I've used a copy of the existing server running cobudget, a t2.small.

These notes are work in progress and not to be trusted!!!

Install docker

apt-get update
apt-get install -y apt-transport-https ca-certificates curl software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | apt-key add -
add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
apt-get update
apt-get install -y docker-ce

Make a dbdump directory to contain the database dumps we want to reload

Login to the relevant docker repo

Get the cobudget docker image

sudo docker pull 041454725975.dkr.ecr.us-west-2.amazonaws.com/cobudget

Create a network, start the database and the cobudget container

sudo docker network create --driver bridge cobudget
sudo docker run --network=cobudget --name=db -v /vagrant:/dbdump -e POSTGRES_DB=cobudget_development -e POSTGRES_USER=ubuntu -e POSTGRES_PASSWORD=<password> -d postgres:9.6

(Please note this database will not store data after the container crashes. Should be fixed) (Please also note it uses user ubuntu, which is foolish. It might as well use a user cobudget so it has the same owner as the production database)

Given the dbdump directory has a database dump called cobudget-prod-171129, restore this to the database

sudo docker exec -it db psql -U ubuntu -d cobudget_development -f /dbdump/cobudget-prod-171129

Start the cobudget container, start delayed jobs and mailcatcher

sudo docker run --network=cobudget --name=cobudget -e DATABASE_URL=postgres://ubuntu:pw@db/cobudget_development -p 3000:3000 -p 1080:1080 -d cobudget rails s -b 0.0.0.0
sudo docker exec -it cobudget bin/delayed_job start
sudo docker exec -it cobudget mailcatcher --http-ip 0.0.0.0

Cobudget in now running on port 3000 and mailcatcher on port 80

Installing and running kong from a container

Start the kong database and run migrations

sudo docker run -d --name kong-database -p 5432:5432 -e "POSTGRES_USER=kong" -e "POSTGRES_DB=kong" postgres:9.6
sudo docker run --rm --link kong-database:kong-database     -e "KONG_DATABASE=postgres" -e "KONG_PG_HOST=kong-database" -e "KONG_CASSANDRA_CONTACT_POINTS=kong-database" kong:latest kong migrations up

(Please note this database will not store data after the container crashes. Should be fixed)

(Please also not this command use links, which is no longer recommended)

Start kong on the host network and make it listen on port 80

sudo docker run -d --name kong --network=host -e KONG_DATABASE=postgres -e KONG_PG_HOST=localhost -e KONG_PROXY_LISTEN=0.0.0.0:80 kong:latest

Register the cobudget api

curl -s -X POST --url http://localhost:8001/apis --data 'name=cobudget-api' --data 'uris=/cb' --data 'upstream_url=http://localhost:3000'

If the kong server is restarted and the database still runs, it will have the API registered in the database.

Cobudget is now accessible through this server on /cb

(This path can be used for branch-name)

Mailcatcher

If we set up a DNS to mailcatcher.test.cobudget.co (can be done easy by using wildcards), we can give access to mailcacther

curl -i -X POST --url http://localhost:8001/apis/ --data 'name=mailcatcher' --data 'hosts=mailcatcher.test.cobudget.co' --data 'upstream_url=http://localhost:1080'
