You can find the previous part here This blog is being hosted on a Docker container in my homelab (see this post for more details). But the actual machine serving the requests is a Linode VPS. I do this because my ISP uses CG-NAT and therefore I can’t open a port from my home network out to the public internet.https://blog.akjohn.dev/blog/setting-up-a-self-hosted-alternative-to-google-maps-timeline/Sun, 25 Aug 2024 16:40:51 +0530https://blog.akjohn.dev/blog/setting-up-a-self-hosted-alternative-to-google-maps-timeline/I’m a big fan of the Google Maps Timeline feature. I think it’s really cool that I can just go back, let’s say, 2 years in the past and see exactly where I was at that time. Right now, the furthest I can go back in my timeline history is something like 5 years. But I believe the nostalgia factor is going to be much bigger when I’m older and I check back to see what I was doing 30 years ago.https://blog.akjohn.dev/blog/monitoring-docker-containers-using-grafana-influxdb-and-telegraf/Sun, 11 Aug 2024 18:50:04 +0530https://blog.akjohn.dev/blog/monitoring-docker-containers-using-grafana-influxdb-and-telegraf/My homelab has over 40 Docker containers running on it right now. Most of them are open source services like Jellyfin, Paperless-ngx, Uptime Kuma and so on (you can find more like these at r/selfhosted). And a few others are running my personal projects like this blog. One issue you will eventually encounter when running a lot of containers is figuring out if any of them are down. Sure you could run the docker ps -a command and use grep to filter any containers that are down, but this takes time and its kinda annoying to go through the text output line by line.https://blog.akjohn.dev/blog/creating-a-ci-cd-pipeline-for-this-blog/Wed, 10 Jul 2024 18:01:13 +0530https://blog.akjohn.dev/blog/creating-a-ci-cd-pipeline-for-this-blog/This is part of a series of blog posts I’m writing about hosting this blog from my homelab. You can find part 1 here: Hosting a blog from your Homelab My current workflow for creating a new blog post is this: Run a Hugo command to create a new markdown file. Write my content in the file. Run the hugo command to generate the build files. Run a command to create a new docker image based on httpd which will serve the build files.https://blog.akjohn.dev/blog/hosting-a-blog-from-your-homelab/Mon, 01 Jul 2024 13:53:07 +0530https://blog.akjohn.dev/blog/hosting-a-blog-from-your-homelab/This blog is currently being hosted on my homelab in a docker container. I have a Wireguard VPN connecting my homelab and my VPS on Linode. The VPS has Nginx Proxy Manager running in a docker container which is publicly exposed on port 80. Then I added a proxy host in Nginx so that all requests to blog.akjohn.dev gets redirected to the docker container in my homelab. One of the most common roadblocks you’ll face when trying to expose almost anything from your home network to the public Internet is bypassing CGNAT.
