Hello, i’m using the new multicontainer feature. I’ve successfully built and deployed my microservices using the docker-compose below and everything is fine except for the persistent storage: in folder /mnt/data/resin-data i see only “resin-supervisor” but not my services’ folders. root@58bba1f:/mnt/data/resin-data# ls -la total 12 drwxr-xr-x 3 root root 4096 Feb 28 06:08 . drwxr-xr-x 6 root root 4096 Feb 28 06:08 … drwxr-xr-x 2 root root 4096 Mar 11 17:48 resin-supervisor ![image](https://global.discourse-cdn.com/balena/original/1X/30b3ecac862806ee217aecf6245b958abe8f4cba.png) Why? Thank you in advance for your kind help This is my docker-compose.yml: version: ‘2’ services: mynodered: build: ./mynodered expose: - “1880” privileged: true restart: always network\_mode: host volumes: - /mnt/data/resin-data:/data mymosquitto: build: ./mymosquitto expose: - “1883” privileged: true restart: always network\_mode: host volumes: - ‘resin-data:/data’ myinfluxdb: build: ./myinfluxdb expose: - “8086” privileged: true restart: always network\_mode: host volumes: - /mnt/data/resin-data:/data ---

Hi @arturol76, we don’t support volume bind-mount and you should use named volumes instead for persisted data. Something like ```auto volumes: - dirname:/path/inside/container ``` See more in [our docs](https://docs.resin.io/reference/supervisor/docker-compose/) regarding what parts of the docker-compose syntax is supported. ---

To expand on this @arturol76 , you’ll want to make sure you have the named volume defined at the top-level of the `docker-compose.yml`, in addition to the named volume link in the service, which it seems you have correctly defined in your mymosquitto service. Something like: ```auto version: '2' volumes: resin-data: services: mynodered: build: ./mynodered volumes: - 'resin-data:/data' ``` I’ll make sure our [multicontainer docs](https://docs.resin.io/learn/develop/multicontainer/#resin-io-settings) are updated to clarify this. ---

I also get: ``` [Error] Could not parse compose file [Error] Bind mounts are not allowed [Error] Not deploying release. ``` when building this `docker-compose.yml`: ``` version: '2' services: telegraf: image: arm32v7/telegraf:1.5 volumes: - ./etc/telegraf.conf:/etc/telegraf/telegraf.conf:ro ``` Any hint on how to migrate this short syntax to named volumes? I just need my local config file to end up in `/etc/telegraf`. Alternatively, do you recommend building a custom container and copying the config file there? Something like: ``` version: '2' services: telegraf: build: ./mytelegraf ``` and `./mytelegraf/Dockerfile` would look like: ``` FROM arm32v7/telegraf:1.5 COPY ./etc/telegraf.conf /etc/telegraf/telegraf.conf ``` But then I lose the ability to change the configuration on the fly… ---

Hey @lv82, the second way is they way I do it, you can have a look at my [mc-demo](https://github.com/shaunmulligan/mc-demo) project where I add a telegraf service that logs metrics to another backend influx instance. ---

Thanks @shaunmulligan. That sounds reasonable. Nice elaboration on the multicontainer example from the documentation. On a side note, you might want to update the `git clone` line in your `README.md` from: ``` $ git clone git@github.com:resin-projects/simple-server-node.git ``` to: ``` $ git clone git@github.com:shaunmulligan/mc-demo.git ``` ---

@lv82 good catch, I always just copy a template readme 😛 I am actually working on an expansion of this project that includes a services for remote logging (probably [loggly](https://www.loggly.com/product/) ), also wanna make use of the balena `HEALTHCHECK` functionality and generally make a nice “Starter” pack project that will get people going quickly with this type of stuff. ---

thank you @zwalchuk for you reply. I did as you suggested: ![image](https://global.discourse-cdn.com/balena/original/1X/a6627c08a89772b568d3e5c4b08f2726f0572055.png) then i build it and push it to [resin.io](http://resin.io). This is what i can see in the “releases” page: ![image](https://global.discourse-cdn.com/balena/original/1X/6f09fce64664cb2e13babc570d3d85e8b368ea81.png) the mynodered service starts and works as expected. The point is that the /data folder used by nodered is still not persistent: ![image](https://global.discourse-cdn.com/balena/original/1X/e2416638417d894fc0f57ca5f9546f108b106a29.png) indeed, if i connect to the host os, i would expect to find a “mynodered” folder but i don’t see anything: ![image](https://global.discourse-cdn.com/balena/original/1X/4333fc4c6a44d2d11ddfe4b4c536151916862e42.png) What am i doing wrong? ---

Hey @arturol76, We’ve actually changed the way we store persistent data, so now rather than keep it in `/mnt/data/resin-data/`, we create a named volume which can be accessed at `/mnt/data/docker/volumes/_resin-data/_data`. You can use `balena volume ls` to see all named volumes. I’ll add this info to our docs ASAP. ---

You mean the same issue as @arturol76? Have you tried looking in `/mnt/data/docker/volumes/_resin-data/_data`, as @zwalchuk recommends? Your data should be there. ---

Dears @lv82 and @zwalchuk I confirm that my services’ persistent data is now stored in folder /mnt/data/docker/volumes/\_resin-data/\_data Thank you! I will open another thread to ask whether makes sense to have persistent data on a external usb key and how to do that. ---

@lv82 I currently don’t have enough context to help you with why we don’t support them now, but with regards to future support of bind mounts, I’d suggest you subscribe to the issue at [https://github.com/resin-io/resin-supervisor/issues/643](https://github.com/resin-io/resin-supervisor/issues/643), so that you can get live updates of our progress there. ---
