Fn using Postgres

Let's presuppose you don't have even a postgres DB ready.

1. Let's start a postgres instance:

docker run --name func-postgres \
        -e POSTGRES_PASSWORD=funcpass -d postgres

2. Now let's create a new database for Functions

Creating database:

docker run -it --rm --link func-postgres:postgres postgres \
    psql -h postgres -U postgres -c "CREATE DATABASE funcs;"

Granting access to postgres user

docker run -it --rm --link func-postgres:postgres postgres \
    psql -h postgres -U postgres -c 'GRANT ALL PRIVILEGES ON DATABASE funcs TO postgres;'

3. Now let's start Functions connecting to our new postgres instance

docker run --rm --privileged --link "iron-postgres:postgres" \
    -e "DB_URL=postgres://postgres:funcpass@postgres/funcs?sslmode=disable" \
    -it -p 8080:8080 fnproject/functions
