Installation method

Install on Portainer

Import all app templates into your Portainer instance, for easy 1-click deploys

  1. Ensure both Docker and Portainer are installed, and up-to-date
  2. Log into your Portainer web UI
  3. Under Settings → App Templates, paste the below URL
  4. Head to Home → App Templates, and the list of apps will show up
  5. Select Murmur, fill in any config options, and hit Deploy

More install options in our documentation.

Serve Murmur on your own domain behind Caddy, Nginx or Traefik. Fill in your domain and copy the result. It's a starting point, some apps need their own base URL or extra headers set too.

Proxying murmur.example.com to http://murmur:64738

Add this to your Caddyfile

murmur.example.com {
	reverse_proxy http://murmur:64738
}

Check the logs first

Nine times out of ten the logs tell you exactly what went wrong.

  • In Portainer, go to Containers, click the container, then Logs. Or run docker logs murmur
  • Exit codes help too: 137 means killed, usually out of memory. 126 or 127 means the command inside the image is broken.

Port already in use

If deployment fails with "Bind for 0.0.0.0:64738 failed: port is already allocated", something else on your server is using that port.

  • Find what's using it: sudo ss -tlnp | grep :64738
  • Stop the other service, or pick a different host port. In 64738:64738 only the left number is yours to change, the right one belongs to the app.

Running but the page won't load

The container is up but nothing appears in your browser.

  • Use your server's real IP: http://your-server-ip:64738. The 0.0.0.0 link Portainer shows isn't a real address.
  • Give it a minute after first deploy, murmur can take a while to initialise.
  • Make sure your firewall allows the port, e.g. sudo ufw allow 64738

Permission denied on volumes

If the logs show "permission denied", the app can't write to its data folder on the host.

  • Fix the ownership: sudo chown -R 1000:1000 /etc/localtime:ro (and the same for the other mapped folders)
  • Or set the PUID and PGID variables (defaults 1000:1000) to match your own user, found with id $USER

Image won't pull

Test the pull directly on the host: docker pull yhaenggi/murmur:1.3.4

  • "manifest unknown" means the tag no longer exists.
  • "toomanyrequests" is the Docker Hub rate limit. Log in with docker login to raise it.
  • "no space left on device" means a full disk. Reclaim space with docker system prune

"exec format error"

This means the image was built for a different CPU architecture than your server.

  • This image supports: amd64, arm64, arm/v7, arm, arm64/v8
  • Check yours with uname -m: x86_64 is amd64, aarch64 is arm64. Raspberry Pi and other ARM boards are the usual culprits.

Container keeps restarting

The unless-stopped restart policy relaunches the app after every crash, so the real error can scroll past.

  • Check the logs right after a restart, the last few lines before it died are the useful ones.
  • Get the exit code with docker inspect murmur --format '{{.State.ExitCode}}'
  • Still stuck? Redeploy once with the restart policy set to no so the failure stays visible.

Raise an issue

Found something which isn't working as it should? Here's how to report it.

A single container

Murmur runs as one container, the simplest kind of app here. Just the one image to pull and nothing else wired up alongside it.

The app image

An image is the app packed up ready to go, everything Murmur needs bundled into one download. This template pulls yhaenggi/murmur:1.3.4, which Docker fetches once (about 60 MB) and then starts your own copy from.

Where the image comes from

Docker pulls its images from registries, public libraries of ready-built apps. Murmur's comes from Docker Hub, published by yhaenggi.

Version tags

The bit after the colon in the image name is the version tag. This one pins 1.3.4, so every redeploy gives you that exact build until you bump it yourself.

Which machines it runs on

Every image is built for particular CPU types. This one ships for amd64, arm64, arm/v7, arm, arm64/v8, so it runs on both regular x86 servers and ARM boards like a Raspberry Pi.

Ports

A port is the door the app answers on. A mapping like 64738:64738 means it's reachable on port 64738 of your server, where the left number is yours to change and the right one belongs to the app. It opens:

  • 64738:64738
  • 64738:64738 over UDP

Volumes

A volume is where Murmur keeps its files so they survive an update or a restart. Without one, anything it saves would sit inside the container and vanish the moment it's recreated. This template mounts:

  • /etc/localtime from /etc/localtime:ro on the host
  • /opt/murmur/config from /portainer/Files/Config/Murmur on the host
  • /opt/murmur/data from /portainer/Files/Murmur/data on the host
  • /opt/murmur/log from /portainer/Files/Murmur/log on the host

Environment variables

Environment variables are the settings you hand over when you deploy, things like a password or a timezone. Murmur takes 3 of them, all with defaults you can leave alone or tweak:

  • PUID, defaults to 1000
  • PGID, defaults to 1000
  • TZ, defaults to America/New_York

Restart policy

The restart policy here is unless-stopped, so Docker restarts Murmur after a crash or reboot, but leaves it off when you stop it on purpose. You can change this on the deploy screen. The choices are no (never restart), on-failure (only after a crash), unless-stopped (restart unless you stop it), and always (bring it back no matter what).

Users and permissions

The PUID and PGID settings tell it which user and group to act as on your host. Point them at your own account (find yours with id $USER) so the files it writes into your mounted folders come out owned by you rather than root.

Networking

Nothing custom is set, so Murmur sits on Docker's default bridge network: its own private space that reaches the outside world only through the ports it publishes.

Container name

Once it's deployed, Portainer names the container murmur. That's what you'll spot in the containers list and use in commands like docker logs murmur.

Platform

The platform is linux, the kind of system the container is built to run on. Docker and Portainer handle this on a normal Linux server.

Portainer app templates

Zooming out, this whole page comes from a Portainer app template: a short recipe telling Portainer how to set Murmur up. Add the template list to Portainer once, then deploying Murmur is a click rather than a wall of config.
