njuicsgz / docker-keystone

A Dockerfile to build openstack keystone

How to build

docker  build --rm -t="krystism/openstack-keystone" .

Environment Variables

you can pass these arguments using docker run -e to override default value.

• MYSQL_ROOT_PASSWORD
• OS_TENANT_NAME : default "admin"
• OS_USER_NAME : default "admin"
• OS_PASSWORD : default "ADMIN_PASS"
• OS_ADMIN_EMAIL : default "[e-mail]"

Start a keystone instance

Before start a keystone instance, we also need mysql database to store data.

mkdir -p /pdata/docker/mysql
docker run --name mysql -p 23306:3306 -v /pdata/docker/mysql:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=Letmein123 -h mysql -d njuicsgz/mysql:5.5

Then we should link the database, create a new keystone instance as follow:

docker run -d \
  --link mysql:mysql\
  -e OS_TENANT_NAME=admin \
  -e OS_USERNAME=admin \
  -e OS_PASSWORD=ADMIN_PASS \
  -p 35357:35357\
  -p 5000:5000 \
  --name keystone -h keystone krystism/openstack-keystone

It may takes some time to execute initscript, you just need to do is wait about 5s, you can use docker logs to fetch some info from the instance, once the work is done, you can check if it really works:

docker exec -t -i keystone bash
cd /root
source admin-openrc.sh
keystone user-list

You need to set /etc/hosts if you want access keystone from external host domain:

# echo '10.2.240.12 keystone' >> /etc/hosts

PS: if you have config KEYSTONE_HOST=10.2.240.12 when starting container 'http://${KEYSTONE_HOST}:35357/v2.0', the WIP can not be accessed in the container。

Enjoy!
