Docker is a software technology that provides operating-system-level virtualization. In this page, we present some tools that are specifically designed to use Docker on Grid'5000.
Installing Docker from a node
You can install and use Docker from a node with the standard environment by following these instructions:
- Reserve a node
(you can also use option
-t deploy and Kadeploy if you prefer)
- Install Docker
The script g5k-setup-docker, available from the standard environment, installs Docker locally. Option -c makes docker command available without needing to log out and reconnect to the node
- Run Docker
You can now check that Docker is up and running
Using docker-machine and docker-g5k
The Spirals Team in Lille developped two tools to ease Docker usage on Grid'5000:
- a docker-machine driver
- the docker-g5k program
- Manage a node with docker-machine
The driver for docker-machine allows you to reserve a node on Grid'5000 and to install a Linux image and Docker Engine on it, from your computer and in one single command.
The reserved node is then available from commands like
docker-machine ssh (standard ssh commands don't work when nodes are reserved with docker-machine).
- Create a Swarm with docker-g5k
The docker-g5k program allows you to reserve several nodes, possibly on different sites, and to install a Linux image and Docker Engine on each node, in one single command. This command configures a Swarm, i.e. a set of Docker containers distributed over several nodes that communicate with each other.
Managing Docker images ?
We recommend the following ways to manage Docker images on Grid'5000:
- Use docker load/save
You can use
docker load and
docker save commands with .tgz docker images stored in your home (or elsewhere). Each user's home is available (NFS mounted) from any node deployed with the standard environment.
- Use Inria private registry
- Use a persistent VM
If you need to create your own private registry, you can request a persistent Virtual Machine.
