Full Description

FreeIPA server in Docker

This repository contains the Dockerfile and associated assets for
building a FreeIPA server Docker image from the official yum repo.

Install docker 1.10+:

yum install -y docker

Start the service:

systemctl start docker

To build the image, run in the root of the repository:

docker build -t freeipa-server .

The repository contains multiple Dockerfiles for various
operating systems. Use -f option to docker build to pick
different than default target.

Create directory which will hold the server data:

mkdir /var/lib/ipa-data

On SELinux enabled systems,

setsebool -P container_manage_cgroup 1

might be needed to enable running systemd in the containers.

You then run the container with

docker run --name freeipa-server-container -ti \
   -h ipa.example.test \
   -v /sys/fs/cgroup:/sys/fs/cgroup:ro \
   --tmpfs /run --tmpfs /tmp \
   -v /var/lib/ipa-data:/data:Z freeipa-server [ opts ]

The list of options [opts] can start with exit-on-finished to stop
the container after successfully configuring the server in the container
(useful for testing), or no-exit to keep the container running even
if the initial configuration fails (useful for debugging).

Standard ipa-server-install will be started and you can configure
the server. The docker run invocation also accepts command line
parameters that will be passed to ipa-server-install, so
unattended invocation is possible, for example with

docker run --rm -e PASSWORD=Secret123 -h ipa.example.test \
    freeipa-server exit-on-finished -U -r EXAMPLE.TEST --no-ntp

Optionally, you can put into the directory mounted into /data
(/var/lib/ipa-data in this example) a file


with command line parameters to ipa-server-install command,
for example


and these options will also be used as parameters to ipa-server-install.

If you want to instruct the container to create a replica, specify the
command in the docker run parameters:

docker run --name freeipa-server-container -ti \
   -h ipa.example.test \
   -v /sys/fs/cgroup:/sys/fs/cgroup:ro \
   --tmpfs /run --tmpfs /tmp \
   -v /var/lib/ipa-data:/data:Z \
   freeipa-server ipa-replica-install [ opts ]

The options will be passed to ipa-replica-install in the container.
You can also put options to file


in the directory mounted to /data to this directory, for example with


If your setup is of Domain Level < 1, GPG-encrypted replica information
file is also needed in the directory mounted to /data.

If the above commands fail with error about invalid value for
flag -v and bad format for volumes, run

chcon -t svirt_sandbox_file_t /var/lib/ipa-data

or use semanage fcontext and restorecon, and use -v option
without the :Z part.

The option --name assigns the container a name that can be used
later with docker start, docker stop and other commands.
Command ipa-server-install is invoked non-interactively the first
time the container is run.

The -ti parameters are optional and are used for get a terminal,
for interactive configuration sessions.

The container can the be started and stopped:

docker stop freeipa-server-container
docker start -ai freeipa-server-container

If you want to use the FreeIPA server not just from the host
where it is running but from external machines as well, you
might want to use the -p options to make the services accessible
externally. You will then likely want to also specify the
IPA_SERVER_IP environment variable via the -e option to
define what IP address should the server put to DNS as its
address. Starting the server would then be

docker run -e IPA_SERVER_IP= -p 53:53/udp -p 53:53 \
    -p 80:80 -p 443:443 -p 389:389 -p 636:636 -p 88:88 -p 464:464 \
-p 88:88/udp -p 464:464/udp -p 123:123/udp -p 7389:7389 \
-p 9443:9443 -p 9444:9444 -p 9445:9445 ...

If you have existing container with data volume, it should be safe
to shut it down and run new one based on newer image, with the same
data directory bind-mounted to /data. The container will detect
that it is running with data produced by different image and attempt
to upgrade the configuration and data. Of course, keeping backup
of the data directory for cases when the upgrade process fails
is recommended.

Configuring and running with atomic

On platforms with atomic command available, the container can be
configured with

atomic install [ --name $THE_NAME ] freeipa-server \
[ keywords for docker operation ] \
[ ipa-server-install | ipa-replica-install ] \
[ opts ]

The keywords for docker operations are:

net-host - docker run --net=host, also uses host's hostname
publish - docker run -p 443:443 ... ; publish all ports of the IPA
          container on host's interfaces
cap-add $CAPABILITY - docker run --cap-add=$CAPABILITY

The container will use /var/lib/$THE_NAME to store the configuration
and data. It the gets started with

atomic run [ --name $THE_NAME ] freeipa-server

Version 1.12 of atomic is needed.

IPA-enrolled client in Docker

There are multiple *-client branches named after OS they are
based on. Check out the branch you prefer and in the root of the
repository, run:

docker build -t freeipa-client .

To run the client container, run it with correctly set DNS
and hostname in the IPA domain, or you can link it to the
freeipa-server container directly:

docker run --privileged --link freeipa-server-container:ipa \
    -e PASSWORD=Secret123 -ti freeipa-client

The first time this container runs, it invokes ipa-client-install
with the given admin password.


The container scripts provide some options for debugging:

  • Enable shell script tracing in both the top-level init-data script
    and the ipa-server-configure-first script by setting the
    $DEBUG_TRACE environment variable.

  • Disable container exit after script failure by setting the
    $DEBUG_NO_EXIT environment variable. After failure, the
    container will continue running, and can be entered for debugging
    with e.g. docker exec -it freeipa-server-container bash.

Example usage:

docker run [...] -e DEBUG_TRACE=1 -e DEBUG_NO_EXIT=1 freeipa-server
