It has been over a year now that I migrated my 2 blogs on full Docker-hosting and I wanted it to be as simple as possible for several reasons:
- Docker is easy to work with and to maintain
- Everything is Dockerizable
- I don't want to spend more than an hour every month or so to upgrade my stacks
At work, we previously used CoreOS to deploy a fleet of Dockerized apps but it was hard to maintain but more specifically, CoreOS is designed for distributed apps, which is not the case of this blog.
So, I searched for a simpler way to just run a Docker container but I did not want to start from a Linux distro (CentOS or Ubuntu) and install Docker on the top of it, that too would require some system maintenance...
Quickly enough, I scripted everything I could on my end (and I'm sure there's more to do) but today, I just upgraded all my stack within a few commands.
I host my 2 blogs at the lowest cost ever:
- $5 per month
- cost of the domain names
- (days of research, trials, coding, etc.)
My first iteration was a bit cumbersome because once I cloned my blog repos on RancherOS I needed to build the Docker images locally: which could use disk space and generate a CPU spike...
Then I remembered that DockerHub offers 1 private repository: perfect!
Now, when I need to upgrade my containers, I do it on my laptop, test them, then push the new images on DockerHub. From RancherOS, I only run a git pull and restart my Docker service.
If you have any questions or suggestions, please go ahead! Thanks for reading.
Left to do
- Automate Docker image builds
- Import blog themes automatically
