The Kullo Server

Kullo server written in Go.

Requirements

• Go version 1.2
• PostgreSQL server 9.3+

Setup GOPATH

Create a new folder where your go sources and packages will be stored:

mkdir ~/go
cd ~/go
mkdir bin pkg src

Define GOPATH:

# add this to your ~/.bashrc or ~/.zshrc
export GOPATH="${HOME}/go"

Open a new shell or source the edited file to apply changes.

Setup: Get sources

Initial checkout of private repository:

cd $GOPATH/src
mkdir -p bitbucket.org/kullo
cd bitbucket.org/kullo
git clone git@bitbucket.org:kullo/server.git

Get, update and build dependencies:

cd $GOPATH/src/bitbucket.org/kullo/server
make update
make

Install PostgreSQL

Ubuntuusers Wiki: PostgreSQL

Install server package

Ubuntu:

sudo apt-get install postgresql

Fedora:

sudo yum install postgresql-server

Create database cluster

Ubuntu:

Cluster 'main' is created automatically.

Fedora:

sudo postgresql-setup initdb

Make postgres locally accessible

Edit pg_hba.conf (Ubuntu: /etc/postgresql/9.3/main/, Fedora: /var/lib/pgsql/data/) so that the following line is present and no other line matches the first 4 columns:

host    all             all             127.0.0.1/32            md5

Afterwards, start postgres:

sudo service postgresql start

Database passwords

The current database passwords can be read from the ansible configuration:

cd workspace/ansible
ansible-vault view --vault-password-file=vault-password.txt roles/kullo-server/vars/main.yml

The password for the kullo user should be stored in ~/.pgpass.

Create database

Create database application user and application database

sudo -u postgres createuser -P kullo
sudo -u postgres createdb -O kullo kullo

Set database settings

cd $GOPATH/src/bitbucket.org/kullo/server
vi config/dbconf.yml

Install goose

go get -u bitbucket.org/liamstask/goose/cmd/goose

Check migration status:

cd $GOPATH/src/bitbucket.org/kullo/server
./goose.sh -env <environment> status

Migrate migrations if necessary.

./goose.sh -env <environment> up

Start server locally

The Kullo server must be started from the right working directory in order to find config files like config/dbconf.yml.

cd $GOPATH/src/bitbucket.org/kullo/server
make && ./kulloserver -env <environment>

Running integration tests

Once:

sudo -u postgres createuser -P kullotest
sudo -u postgres createdb -O kullotest kullotest
./goose.sh -env integrationtest up

virtualenv /path/to/new/venv
source /path/to/new/venv/bin/activate
pip install -r tests/requirements.txt

Every time, in one shell:

make && ./kulloserver -env integrationtest

Every time, in another shell:

source /path/to/new/venv/bin/activate  # if not yet activated in this shell
make integrationtest

Deploy to server

As a prerequisite, this needs the tool fabric, which is available from the package repositories of at least Ubuntu and Fedora under the name fabric.

Push a new version to the server

fab

Revert to the previous version

fab rollback
