<p>How can I add a custom <code>config.json</code> and add a custom style <code>/styles/custom.json</code> 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 <code>configMap</code> and <code>volumeMounts</code> the right approach?</p>

<p>I've looked a little deeper into your environment and deployed it on my local cluster, here are my findings:</p>

<ul>
<li>Look where the files end up being mounted when I deploy your yaml as is in your question:</li>
</ul>

<pre><code>$ kubectl get pods
NAME                               READY   STATUS              RESTARTS   AGE
map-tile-server-5c86b677df-wswwz   1/1     Running             0          2s

$ kubectl exec -it map-tile-server-5cb677df-wswwz /bin/bash --
root@map-tile-server-5c86b677df-wswwz:/# ls -l
drwxrwxrwx   3 root root 4096 Apr 10 12:16 config.json
drwxr-xr-x   3 root root 4096 Apr 10 12:16 styles

root@map-tile-server-5c86b677df-wswwz:/config.json# ls -l
lrwxrwxrwx 1 root root 18 Apr 10 12:16 config.json -&gt; ..data/config.json

root@map-tile-server-5c86b677df-wswwz:/styles# ls -l
drwxrwxrwx 3 root root 4096 Apr 10 12:16 custom.json

root@map-tile-server-5c86b677df-wswwz:/styles# cd custom.json/
root@map-tile-server-5c86b677df-wswwz:/styles/custom.json# ls -l
lrwxrwxrwx 1 root root 18 Apr 10 12:16 custom.json -&gt; ..data/custom.json
</code></pre>

<ul>
<li><p>It is creating folders with the file names and inserting your configmaps inside each one.</p></li>
<li><p>In your question you mention you want this files to be placed in <code>/config.json</code> and <code>/styles/custom.json</code>, I'd like to comment two things with you:</p>

<ul>
<li><p>You can't set <code>config.json</code> to mount directly in <code>/</code>, 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 <code>/data</code> dir.</p></li>
<li><p>Although there is a symlink directing the <code>/styles/custom.json/custom.json</code> file to <code>data/custom.json</code>, It is good to warn you that:</p></li>
</ul>

<p><strong>if you mention the path <code>/style/custom.json</code> in your <code>config.json</code> it will not find the file there</strong>.</p></li>
</ul>

<p>Here you can see an example provided in Kubernetes Documentation on <a href="https://kubernetes.io/docs/tasks/configure-pod-container/configure-pod-configmap/#add-configmap-data-to-a-specific-path-in-the-volume" rel="nofollow noreferrer">How to Mount ConfigMaps as Files</a></p>

<ul>
<li>These are the changes I made to your yaml to move the <code>custom.json</code> file to the intended path:</li>
</ul>

<pre><code>          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
</code></pre>

<ul>
<li>Now let's test it:</li>
</ul>

<pre><code>$ 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 -&gt; ..data/config.json

root@map-tile-server-5cd7694b74-s6g6g:/styles# ls -l
lrwxrwxrwx 1 root root 18 Apr 10 12:27 custom.json -&gt; ..data/custom.json
</code></pre>

<p>Now the files are in the intended location.</p>

<ul>
<li>My suggestion to easy your management later, would be for example mounting to:</li>
</ul>

<pre><code>          volumeMounts:
            - name: map-tile-server-config
              mountPath: /data/config
            - name: map-tile-server-style-config
              mountPath: /data/styles
</code></pre>

<ul>
<li>Would output everything inside data folder:</li>
</ul>

<pre><code>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
-rw-r--r-- 1 root root 24244224 Apr 10 13:22 zurich_switzerland.mbtiles
root@map-tile-server-6b5fc64fd6-6g2wb:/data# ls config
config.json
root@map-tile-server-6b5fc64fd6-6g2wb:/data# ls styles
</code></pre>
