In this part I want to have most viral services up and running on the final hardware.

Debian, RAID-1, HTTPS, Docker

Installing Debian 9.5 was as easy as always. One additional step that I learned was software RAID. The install script (text mode!) is very easy to use to I manage to setup everything with no problems.

Apache2 + Let's Encrypt SSL using cert-bot. That part was also straightforward. I still don't know how to make this work with Docker containers (Ghost in particular). But this is something for part #5 :)

Once the Docker-CE was installed. Bringing back all the containers was as easy as it can be. I copied the old volumes (mapped to /home/domain) and all docker services were online as before. This was the fastest migration ever.

Creating configs/folders/ownerships for Apache is easy but time consuming (as I needed to change my old .conf files). This part will take more time but I will remove any not needed sites in the process.

Dockerize All The Things!

Containers are the future.

Docker containers

Apache domains use ProxyPass for ports 8080-8087. Most of the sites are online. There are still lot of * subdomains waiting for resurrection.

Recovery Scenario

I was able to recover all databases and configs for docker sites. I fixed a lot of mistakes in my recovery scenarios. And I already tested them on living organism. I don't have backups configured yet. But RAID-1 covers my ass.


With new drives I have a lot of free space. With whole Debian 9.5 and dockers it only takes 6.6GB so far :)

$ df -h

udev            2.0G     0  2.0G   0% /dev

tmpfs           2.0G     0  2.0G   0% /sys/fs/cgroup
tmpfs           396M     0  396M   0% /run/user/1000

Less than 1GB memory is used. And the CPU is mostly at 1-3%.

What's Missing?

I still have few things to add. Syncthing, automatic backups, offline backups, subdomains, load monitoring, UPS alerts.
