Installation instructions

The following instructions will setup a development environment for commissaire.

If something does not work as expected, please create an issue or propose a PR.

Prepare environment

The environment can be installed on a base Fedora 24 installation.

First install the required packages:

$ sudo dnf update -y
$ sudo dnf install -y etcd redis
$ sudo dnf install -y @development-tools redhat-rpm-config
$ sudo dnf install -y python3 python3-virtualenv

Next enable the etcd and redis services:

$ sudo systemctl enable etcd redis
$ sudo systemctl start etcd redis

Pull repositories

Commissaire consists of several projects that either provide common code or the actual services. You can clone the repos by following the example below:

$ mkdir commissaire-projects
$ cd commissaire-projects
$ git clone https://github.com/projectatomic/commissaire
$ git clone https://github.com/projectatomic/commissaire-service
$ git clone https://github.com/projectatomic/commissaire-http
$ git clone https://github.com/projectatomic/commctl

After this we will install each project to setup a development environment.

Create VirtualEnv

In the commissaire-projects directory you previously created (Pull Repositories, above) create the devel virtualenv:

$ virtualenv-3.5 devel
$ . ./devel/bin/activate

Continue executing the following commands in the virtualenv you just created.

NOTE: For zsh users, you may need to run the rehash shell builtin after you pip install each project so that the commands are available in your $PATH.

Install Commissaire

$ cd commissaire
$ pip install -e .
$ cd ..

Install Commissaire Service

$ cd commissaire-service
$ pip install -e .
$ ../commissaire/tools/etcd_init.sh

Edit your storage configuration to point to your etcd instance:

$ cp conf/storage.conf mystorage.conf

Note: Point server_url to http://127.0.0.1:2379 (not https)

Start the service

$ commissaire-storage-service -c mystorage.conf &
$ cd ..

Install Commissaire Server

$ cd commissaire-http
$ pip install -e .  # Install commissaire-http into the virtualenv

Edit the configuration to point to your redis instance

$ cp conf/commissaire.conf config.conf

Note: If locally installed you do not need to change anything

Start the service:

$ commissaire-server -c config.conf &
$ cd ..

Run testcases for Commissaire Server

Note: that you can use tox to run testcases for this project.

Install using:

$ pip install tox

and then, from the commissaire-http folder, run the following command:

$ tox -v -e py35

Verification

After this the API will be available at http://127.0.0.1:8000/. To verify it works, we will use the initial user a with pass a.

$ curl -u "a:a" -X GET http://127.0.0.1:8000/api/v0/clusters/

Using commctl

$ cd commctl
$ pip install -e .
$ cd ..

Edit the configuration:

$ vi ~/.commissaire.json

{
    "username": "a",
    "password": "a",
    "endpoint": "http://127.0.0.1:8000"
}

To query the known clusters:

$ commctl cluster list

In our case this should now return No object found
