Getting started with GitLab-CE. Part 2: User accounts, SSH access
In my previous blog post, we installed GitLab-CE and did some post configuration. In this blog post, we’ll continue to create user accounts and set up SSH to the git repository.
In the next blog posts will add code to GitLab and set up GitLab runners on different Operating systems.

CI/CD Platform Overview
When you want or need to use CI/CD you have a lot of CI/CD platforms where you can choose from. As with most “tools”, the tool is less important. What (which flow, best practices, security benchmarks, etc) and how you implement it, is what matters.
One of the most commonly used options is Jenkins.
I used and still use Jenkins and created a jenkins build workstation to build software and test in my homelab a couple of years back.
Jenkins started as Hudson at Sun Microsystem(RIP). Hudson is one of the many open-source projects that were started at Sun and killed by Oracle. Jenkins continued as the open-source fork of Hudson.
Jenkins has evolved. If you need to do more complex things you probably end up creating a lot of groovy scripts, nothing wrong with groovy. But as with a lot of discussions about programming, the ecosystem (who is using it, which libraries are available, etc) is important.
Groovy isn’t that commonly used in and known in the system administration ecosystem so this is probably something you need to learn if you’re coming for the system administrator world ( as I do, so I learnt the basics of Groovy this way ).
The other option is to implement CI/CD using the commonly used source hosting platforms; GitHub and GitLab.
- On GitHub we have GitHub Actions.
- On GitLab there is GitLab CI/CD.
Migrate from ezjail to BastilleBSD part 2: Migrate the Jails
How to migrate Jails from ezjail to BastilleBSD
In my previous blog post, I reviewed BastilleBSD. In this post, we go through the required steps to migrate the Jails from ezjail to BastilleBSD.
ezjail test Jail
To test the Jail migration, we’ll first create a test Jail with ezjail. This test Jail will migrate to a BastilleBSD Jail.
Create the test ezjail Jail
We use the ezjail-admin create staftestje001 'vtnet0|<ip>' command to create the test Jail.

Introduction to BastilleBSD
What are “containers”?
Chroot, Jails, containers, zones, LXC, Docker
I use FreeBSD on my home network to serve services like email, git, fileserver, etc. For some other services, I use k3s with GNU/Linux application containers.
The FreeBSD services run as Jails. For those who aren’t familiar with FreeBSD Jails. Jails started the whole concept of “containers”.
FreeBSD Jails inspired Sun Microsystems to create Solaris zones.
If you want to know more about the history of FreeBSD Jails, Solaris zones and containers on Un!x systems in general and the challenges to run containers securely I recommend the video;
“Papers We Love: Jails and Solaris Zones by Bryan Cantrill”
Sun took containers to the next level with Solaris zones , allowing a fine-grade CPU and memory allocation.
On GNU/Linux LXC was the most popular container framework. …Till Docker came along.
