I. Short Description

  Getting started in Arukas with CentOS.

II. Environment & Building CentOS

  A host running Centos7.

yum install docker git
systemctl start  docker.service
git clone https://github.com/arukasio/docker-hub-images.git
cd docker-hub-images/quickstart-centos
docker build --no-cache --tag quickstart-centos .

III. Get API key

  See here: https://app.arukas.io/settings/api-keys

IV. Deploying to Arukas

  You can login use "Public key authentication"

docker run \
    --rm \
    -e ARUKAS_JSON_API_TOKEN=<APIT_TOKEN> \
    -e ARUKAS_JSON_API_SECRET=<SECRET_KEY> \
    arukasio/arukas run --instances=1 --mem=512 --envs AUTHORIZED_KEY="`cat ~/.ssh/id_rsa.pub`" --ports=22:tcp arukasio/quickstart-centos

  or "Username / Password"

docker run \
    --rm \
    -e ARUKAS_JSON_API_TOKEN=<APIT_TOKEN> \
    -e ARUKAS_JSON_API_SECRET=<SECRET_KEY> \
    arukasio/arukas run --instances=1 --mem=512 --ports=22:tcp arukasio/quickstart-centos -e ROOT_PWD=<YOUR_PWD>

V. Login CentOS

  Login to the control panel, and you will see the CentOS is running on Arukas now, like this:

  You can login use Xshell, but note that the port is not 22, but 31303 which was mapping out.

VI. Trouble Shooting

1、Cannot connect to the Docker daemon
You should start docker service first as root, like

sudo start service docker
