Vagrant + Ansible for FreeIPA and Dogtag PKI

Authors: Christian Heimes [email protected]

The playbook is partly inspired by and based on Adam Young's rippowam https://github.com/admiyo/rippowam.

Requirements

The FreeIPA setup needs about 3 to 3.5 GB of free RAM and 6 to 7 GB disk space.

Install dependencies

sudo dnf install ansible libvirt vagrant vagrant-libvirt vagrant-hostmanager libselinux-python nss-tools krb5-pkinit
sudo systemctl enable libvirtd
sudo systemctl start libvirtd
sudo usermod -G libvirt -a YOUR_USER

Either restart your session or use newgrp to join the new user group (current shell only).

$ newgrp libvirt

passwords

The default password for the users root and vagrant, FreeIPA's admin user, 389-DS, PKI CA and PKI KRA is Secret123. The Directory Manager password is DMSecret456.

FreeIPA

$ cd ipa
$ ./setup.sh

Vagrant's multi-machine setup can run into a race condition and starts provisioning before all machines have a new SSH key. vagrant up --no-provision followed by vagrant provision is more stable. Sometimes the initial provision fails to configure the client or replica. A second provisioning run with vagrant provision fixes most issues.

The FreeIPA playbook deploys six machines:

• ipamaster (master.ipa.example) with CA and KRA
• ipareplica1 (replica1.ipa.example)
• ipaclient1 (client1.ipa.example)
• ipafilesserver (fileserver.ipa.example) for NFS, Samba and Apache demos
• ipavpnserver (vpn.ipa.example) for ocserv VPN
• ipaidpserver (idp.ipa.example) for Ipsilon IdP

When the machines are up, you can acquire a Kerberos ticket and start a local instance of Firefox to explore the WebUI. The admin password is Secret123.

$ bin/ipa_kinit admin
$ bin/ipa_firefox
$ bin/ipa_ssh [email protected]

FreeIPA test server

$ cd ipatests
$ ./setup.sh

One test machine:

• ipatestmaster (master.ipatests.local) with CA and KRA

Dogtag PKI

$ cd pki
$ vagrant up

The playbook for Dogtag PKI deploys 389-DS, a CA and a KRA in one VM.

• pki_server (dogtag.pki.example)

Python 3 dependencies

There is a shell script in pki/rpms that will download some dependencies.

forceful cleanup

rm -rf /var/lib/pki/ /var/log/pki/ /etc/sysconfig/pki-tomcat/ /etc/sysconfig/pki/tomcat/pki-tomcat/ /root/.dogtag/pki-tomcat /etc/pki/pki-tomcat/

Vagrant quick manual

create VM

$ cd pki
$ vagrant up

Provision the VM again

For example to update RPMs

$ vagrant provision

Log into VM

$ vagrant ssh <machine>

Destroy VM

$ vagrant destroy

Install custom RPMs

Copy or symlink files or directories with RPMs into pki/rpms or ipa/rpms and set custom_rpms to True. The Ansible playbook will pick up all RPMs (even in symlinked and nested directory structures) and install them.

When something fails

$ sudo systemctl restart libvirtd.service
$ vagrant provision

Provision non Vagrant machines

Create an inventory.cfg

[ipaserver_master]
master.domain.example

[ipaserver_replica]
replica1.domain.example
replica2.domain.example

[ipa_client]
client1.domain.example
client2.domain.example
client3.domain.example

and shell script

#!/bin/sh
set -ex

PKI_VAGANS="/path/to/pki-vagans"
IPA_DOMAIN="domain.example"

export ANSIBLE_CONFIG=${PKI_VAGANS}/ansible/ansible.cfg

ansible-playbook \
    -i inventory.cfg \
    ${PKI_VAGANS}/ansible/ipa-playbook.yml \
    -vv \
    --extra-vars='{"package_install":true,"package_upgrade":true,"coprs_enabled":[],"ipa_replica_kra":false,"ipa_domain": "'${IPA_DOMAIN}'"}'
