+# Introduction
+I'm using [Diun](https://github.com/crazy-max/diun) to be notified about outdated Docker container. Today I was notified about an outstanding update for [acme.sh](https://github.com/acmesh-official/acme.sh). I'm using acme in various variants but this container was running on my Synology, outside the management provided by [Dockge](https://github.com/louislam/dockge), so I had to update the container manually.
+
+# Update procedure
+Login to your Host via SSH and become root. Update to the latest image by using `docker pull neilpang/acme.sh`. Here's an example call from my machine:
+
+```bash
+ash-4.4# docker pull neilpang/acme.sh
+Using default tag: latest
+latest: Pulling from neilpang/acme.sh
+f18232174bc9: Already exists

+Status: Downloaded newer image for neilpang/acme.sh:latest
+docker.io/neilpang/acme.sh:latest
+```
+
+Now you'll have to recreate the currently running container. You can check if your container is running by using `docker ps|grep acme`. Again an example output:
+
+```bash
+ash-4.4# docker ps|grep acme
+1144de4611aa   187c1f47ec28                                   "/entry.sh daemon"       15 months ago    Up 2 weeks                                                            acme
+```
+
+For the recreation you'll need to know how you'll originally started your container. I did this manually when I setup acme for the first time using [these instructions]({{< ref "/post/2023/10/12/configure-lets-encrypt-acme-with-ionos-api-in-openwrt" >}}). My only custom modification was that I'm referencing a volume to keep my certificates.
+
+You can now either stop, remove and recreate the container or stop, remove and recreate it in a docker-compose file. I've chosen the latter variant to spare me from future manual updates. My `docker-compose.yml` looks like this:
+
+```yaml
+services:
+  acme:
+    image: neilpang/acme.sh:latest
+    container_name: acme
+    restart: unless-stopped
+    command: daemon
+    volumes:
+      - /volume1/docker/acme:/acme.sh
+networks: {}
+```
+
+Now I can just hit update in Dockge and I'm getting my container updated.
+
+# Conclusion
+I have no idea why I did not move acme to a docker-compose file earlier. Updating it this way is way more comfortable.  But the best thing about this update is probably that I've did migrate my setup to Dockge.
