This is currently a work-in-progress. This does not yet result in a working instance of TT-RSS (packetgeek, 1 Aug 2022).

TTRSS in Minikube, on a Ryzen-based mini-PC, with NFS-based persistence

This is for my own education and personal use. Please refer to Antonio Correia's code if you're attempting similar (I do horrible things to other people's code).

Assumptions

In the below, 192.168.2.105 is the IP address of my private Docker registry.

My rig

I'm running a Minikube node on a Coofun mini-PC. It's running Ubuntu Server 22.04 (no GUI). It's configured with NFS-based persistence (a departure from Mr. Correia's configuration). My intent is to track various feeds on Medium, as well as other, more "normal", RSS feeds.

Steps - Creating the images

Grab a copy of the code navigate into the folder for the app container:

git clone https://github.com/packetgeek/K3S-TTRSS
cd K3S-TTRSS/Containers/app

Build the app image via:

docker build -t local/ttrss-app .

Note the "space period" at the end of the above.

Perform similar for the updater, via:

cd ../updater
docker build -t local/ttrss-updater .

Perform similar for the nginx container, via:

cd ../web-nginx
docker build -t local/ttrss-web_nginx

You should now have three images built. Running "docker images" should show something like:

REPOSITORY                        TAG         IMAGE ID       CREATED              SIZE
local/ttrss-web_nginx             latest      745db2243c8f   About a minute ago   23.5MB
local/ttrss-updater               latest      8760f455537b   5 minutes ago        92.6MB
local/ttrss-app                   latest      ad22edabf9ef   7 minutes ago

Retag each image so that the private hosts IP and port are part of the tag name. This can be done via:

docker images
docker tag 745db2243c8f 192.168.2.105:5000/local/ttrss-web_nginx

Perform Step #5 on the other two images. Now running "docker images" should show something like:

192.168.2.105:5000/local/ttrss-web_nginx   latest      745db2243c8f   12 hours ago   23.5MB
local/ttrss-web_nginx                      latest      745db2243c8f   12 hours ago   23.5MB
192.168.2.105:5000/local/ttrss-updater     latest      8760f455537b   12 hours ago   92.6MB
local/ttrss-updater                        latest      8760f455537b   12 hours ago   92.6MB
192.168.2.105:5000/local/ttrss-app         latest      ad22edabf9ef   12 hours ago   92.6MB
local/ttrss-app                            latest      ad22edabf9ef   12 hours ago   92.6MB

Push the image to the local registry via:

docker push 192.168.2.105:5000/local/ttrss-app

Perform step #7 for the other two images.
Push all three images to your local registry.

*** in the following, suggest changing imagePullPolicy from Always to IfNotPresent ***

Edit the ttrss-app.yml file and, in the "image:" line, replace "ajvcorreia/ttrss-app" with "192.168.2.105:5000/local/ttrss-app"
Edit the ttrss-nginx.yml file and, in the "image:" line, replace "ajvcorreia/ttrss-web_nginx" with "192.168.2.105:5000/local/ttrss-web_nginx"
Edit the ttrss-updater.yml file and, in the "image:" line, replace "ajvcorreia/ttrss-updater" with "192.168.2.105:5000/local/ttrss-updater"
Edit ttrss-app-pvc.yml and change "loghorn" to "stadard".
Edit ttrss-db-pvc.yml and change "longhorn" to "standard".
Add the pv sections to both of the pvc files.
Before testing the build, be sure that the following conditions are met:

the local registry is turned on
ttrss-config.yml has been edited

Development is still occurring at this point. Below cannot be used yet.

*** test the build ***

**** need to file a bug with Mr. Correia about two imagepullpolicy lines in his db manifest ***

Installation

Once you have the containers built and stored in a local repo, the following should install TT-RSS in your K8S node. This command should install TTRSS successfully on a kubernetes cluster

kubectl apply -f .

From Mr. Correia's page

Since kubernetes cannot build the containers to run in the pods, I had to build them manually from the official docker-compose repository.

I cloned the original docker compose scripts (https://git.tt-rss.org/fox/ttrss-docker-compose) and modified it to build the individual containers: ajvcorreia/ttrss-app ajvcorreia/ttrss-updater ajvcorreia/ttrss-web_nginx

I had to modify the nginx container to replace the app server name in the nginx.conf on startup as this is only available after kubernetes starts the pod.
