Using Kubernetes for TileServer-GL with custom config and style files - docker

Question

How can I add a custom config.json and add a custom style /styles/custom.json to tileserver-gl using Kubernetes? Here is what I have so far for my kubernetes manifest file. Tileserver-gl is up and running fine but I do not see my custom theme that I defined. It does not look like my custom config.json file is being applied. Is using configMap and volumeMounts the right approach?

I've looked a little deeper into your environment and deployed it on my local cluster, here are my findings:
Look where the files end up being mounted when I deploy your yaml as is in your question:
$ kubectl get pods

It is creating folders with the file names and inserting your configmaps inside each one.
In your question you mention you want this files to be placed in /config.json and /styles/custom.json, I'd like to comment two things with you:
You can't set config.json to mount directly in /, the container will not run because you "overwrite" the / folder. So your config.json needs to stay inside some folder, best practice is to mount directly in /data dir.
Although there is a symlink directing the /styles/custom.json/custom.json file to data/custom.json, It is good to warn you that:
if you mention the path /style/custom.json in your config.json it will not find the file there.
Here you can see an example provided in Kubernetes Documentation on How to Mount ConfigMaps as Files
These are the changes I made to your yaml to move the custom.json file to the intended path:
volumeMounts:
- name: map-tile-server-config
mountPath: /config.json
- name: map-tile-server-style-config
mountPath: /styles
volumes:
- name: map-tile-server-config
configMap:
name: map-tile-server-config
- name: map-tile-server-style-config
configMap:
name: map-tile-server-style-config
Now let's test it:
$ kubectl get pods
NAME READY STATUS RESTARTS AGE
map-tile-server-5cd7694b74-s6g6g 1/1 Running 0 8s
$ kubectl exec -it map-tile-server-5cd7694b74-s6g6g -- /bin/bash
root#map-tile-server-5cd7694b74-s6g6g:/# ls
bin boot config.json data dev etc home lib lib64 media mnt opt proc root run sbin srv styles sys tmp usr var
root#map-tile-server-5cd7694b74-s6g6g:/config.json# ls -l
lrwxrwxrwx 1 root root 18 Apr 10 12:27 config.json -> ..data/config.json
root#map-tile-server-5cd7694b74-s6g6g:/styles# ls -l
lrwxrwxrwx 1 root root 18 Apr 10 12:27 custom.json -> ..data/custom.json
Now the files are in the intended location.
My suggestion to easy your management later, would be for example mounting to:
volumeMounts:
- name: map-tile-server-config
mountPath: /data/config
- name: map-tile-server-style-config
mountPath: /data/styles
Would output everything inside data folder:
owilliam#minikube-usc1a:~/CaseFiles/configmap-json$ k exec -it map-tile-server-6b5fc64fd6-6g2wb -- /bin/bash
root#map-tile-server-6b5fc64fd6-6g2wb:/data# ls
config styles zurich_switzerland.mbtiles
root#map-tile-server-6b5fc64fd6-6g2wb:/data# ls -l
total 23684
drwxrwxrwx 3 root root 4096 Apr 10 13:22 config
drwxrwxrwx 3 root root 4096 Apr 10 13:22 styles
