I am utterly lost on how to use my NVMe SSD for my Postgres data, i.e. /var/lib/postgres/data, in my single-container application on my Jetson Xavier NX SD Card devkit. I have BalenaOS and the containers running from the SD Card, but I would like the database to be persisted and stored on the NVMe. …

Hey @ts-cfield , I know it can be tricky to get storage mounted in a container, but you are definitely on the right track! I could not figure out how to run this script at boot of the container without overriding the entry point for the Postgres/Timescale parent image. The best way in my opinion …

@klutchell , Thank you for the information and guidance. I feel I have learned a massive amount about all of this since I originally posted, but your post has been very helpful. I have the following (untested) init.sh script to mount the NVMe drive at boot of the container/device: #!/env/bin bash …

[image] klutchell: The best way in my opinion is that you DO want to override the existing entrypoint with a small script that does some stuff then calls exec docker-entrypoint.sh . Sorry, but this is not working. As soon as I add an ENTRYPOINT ["/custom-init.sh"] line to my Dockerfile, I get…

I think may have this resolved. There are several points that I appear to have missed in my early attempts. The image must be privileged and have UDEV enabled. The privileged: true key-value must be included in the docker-compose.yml file if attempting to mount the external drive within a multi-co…

Hey @ts-cfield , I think you need to provide the absolute path to your custom init script unless unless you add it to the PATH. COPY custom-init.sh / RUN chmod +x /custom-init.sh # use the absolute path here (or copy the file to /bin or /sbin, etc) ENTRYPOINT ["/custom-init.sh"] Then you can call t…

@klutchell Thank you for help and advice. I used an absolute path for the entrypoint in the Dockerfile. The PostgreSQL/TimescaleDB base image copies their entrypoint script to /usr/local/bin, which makes it accessible from where, so the exec docker-entrypoint.sh "$@"line in the custom-init.sh file d…
