Produktlogo UCS Version 4.0

Docker with UCS

Docker is an open-source project that automates the deployment of applications inside software containers.

Installation

docker packages can be installed with the following commands

ucr set repository/online/component/docker=enabled \
        repository/online/component/docker/unmaintained=enabled
univention-install docker.io

After that, docker is ready to use:

~# docker 
Usage: docker [OPTIONS] COMMAND [arg...]

A self-sufficient runtime for linux containers.

Options:
  --api-enable-cors=false                Enable CORS headers in the remote API
  -b, --bridge=""                        Attach containers to a pre-existing network bridge
                                           use 'none' to disable container networking
  --bip=""                               Use this CIDR notation address for the network bridge's IP, not compatible with -b
  -D, --debug=false                      Enable debug mode
  -d, --daemon=false                     Enable daemon mode
  --dns=[]                               Force Docker to use specific DNS servers
  --dns-search=[]                        Force Docker to use specific DNS search domains
  -e, --exec-driver="native"             Force the Docker runtime to use a specific exec driver
  --fixed-cidr=""                        IPv4 subnet for fixed IPs (ex: 10.20.0.0/16)
                                           this subnet must be nested in the bridge subnet (which is defined by -b or --bip)
  -G, --group="docker"                   Group to assign the unix socket specified by -H when running in daemon mode
                                           use '' (the empty string) to disable setting of a group
  -g, --graph="/var/lib/docker"          Path to use as the root of the Docker runtime
  -H, --host=[]                          The socket(s) to bind to in daemon mode or connect to in client mode, specified using one or more tcp://host:port, 
                                         unix:///path/to/socket, fd://* or fd://socketfd.
  --icc=true                             Enable inter-container communication
  --insecure-registry=[]                 Enable insecure communication with specified registries (no certificate verification for HTTPS and enable HTTP 
                                         fallback) (e.g., localhost:5000 or 10.20.0.0/16)
  --ip=0.0.0.0                           Default IP address to use when binding container ports
  --ip-forward=true                      Enable net.ipv4.ip_forward
  --ip-masq=true                         Enable IP masquerading for bridge's IP range
  --iptables=true                        Enable Docker's addition of iptables rules
  --mtu=0                                Set the containers network MTU
                                           if no value is provided: default to the default route MTU or 1500 if no default route is available
  -p, --pidfile="/var/run/docker.pid"    Path to use for daemon PID file
  --registry-mirror=[]                   Specify a preferred Docker registry mirror
  -s, --storage-driver=""                Force the Docker runtime to use a specific storage driver
  --selinux-enabled=false                Enable selinux support. SELinux does not presently support the BTRFS storage driver
  --storage-opt=[]                       Set storage driver options
  --tls=false                            Use TLS; implied by tls-verify flags
  --tlscacert="/root/.docker/ca.pem"     Trust only remotes providing a certificate signed by the CA given here
  --tlscert="/root/.docker/cert.pem"     Path to TLS certificate file
  --tlskey="/root/.docker/key.pem"       Path to TLS key file
  --tlsverify=false                      Use TLS and verify the remote (daemon: verify client, client: verify daemon)
  -v, --version=false                    Print version information and quit
