cloudhero.io is developing a Docker container service in the cloud. While it's in development, they are offering a free Docker node within which you can run containers. This is perfect for creating a small website.
Beware, cloudhero.io does not guarantee your data will be safe.
In fact, they had a server problem which resulted in total loss of everything I had stored in my Docker containers. Regardless, this is a very handy service, just keep your data backed up.
The following steps show how to:
- Connect your docker installation to the cloudhero.io cluster
- Create a ghost container
- Create a ghost-data container
- Run Ghost persisting data to the ghost-data container
- Update config.js in /var/lib/ghost to point to your cloudhero.io site
Creating the Ghost Site with a Persistent StoreConnect the local docker commands to administer docker on the cloudhero.io cluster:
eval $(curl -s https://portal.cloudhero.io/bootstrap/.../script | sh) docker create -v /var/lib/ghost --name ghost-data ghost /bin/true docker run --name ghost -p 80:2368 --volumes-from ghost-data -d ghost
Configure the persistent store
docker exec -it ghost /bin/bashGet your node name from cloudhero.io, under the account tab. Change config.js to point to http://swarmXXXX.cloudhero.io, restart to pick up the config.
docker restart ghost
Put stuff on your website
open http://swarm1398.cloudhero.io/ghostCreate your login:
Your@email.com, your real (or pen) name.Continue by adding new posts, etc.
Backup data from ghost-data containerIt's pretty hard to get access to the host filesystem from within a container. The simplest way to deal with this is to use an external place to store the data. Accessing the local filesystem from within a container is difficult, using plain hold SCP does the trick.
docker stop ghost docker run -it --volumes-from ghost-data ghost /bin/bashInside the container:
apt-get update;apt-get install -y openssh-client tar zcf /tmp/ghost.tgz /var/lib/ghost scp /tmp/ghost.tgz firstname.lastname@example.org:.
Get data from backup and store it locally
scp email@example.com:ghost.tgz .Restart container
docker start ghost
