conman

conman - [the] container manager

The aim of the project is to implement yet another container manager. Primarily, for the sake of [self-]education. The conman project is heavily inspired by cri-o and the ultimate goal is to make conman CRI-compatible. This will allow to deploy a Kubernetes cluster with conman as a container runtime server.

State of the project

Under active development. Not even close to 0.1.0.

Run it

So far the only tested platform is CentOS 7.

git clone https://github.com/iximiuz/conman.git
cd conman

# Build daemon and client
make bin/conmand
make bin/conmanctl

# Run daemon
sudo bin/conmand

# Prepare dev data
make test/data/rootfs_alpine

# Create containers
sudo bin/conmanctl container create --image test/data/rootfs_alpine/ cont1 -- sleep 100
sudo bin/conmanctl container create --image test/data/rootfs_alpine/ cont2 -- sleep 200

# List containers
sudo bin/conmanctl container list

# Start container 
sudo bin/conmanctl container start <container_id>

# Stop container 
sudo bin/conmanctl container stop <container_id>

# Request container status
sudo bin/conmanctl container status <container_id>

# Remove container 
sudo bin/conmanctl container remove <container_id>

Test it

sudo PATH=/usr/local/bin:$PATH make testunit

# install jq `yum install jq`
# install bats https://github.com/bats-core/bats-core 
sudo PATH=/usr/local/bin:$PATH make testintegration

TODO:

• pick up state of the containers on conman [re]start
• acceptance tests
• shim
  • track container exit code
  • interactive containers (exec, stdin/stdout support)
  • PTY-controlled containers (eg. shell)
  • attach to a running container
