There is currently an issue with read-only mounts in Docker. mount type=bind,source=/path/to/media2,target=/media2,readonly Multiple media libraries can be bind mounted if needed: -mount type=bind,source=/path/to/media1,target=/media1 Replace jellyfin-config and jellyfin-cache with /path/to/config and /path/to/cache respectively if using bind mounts. For a simple setup, it's considered easier to use Bind Mounts instead of volumes. Using host networking ( -net=host) is optional but required in order to use DLNA.īind Mounts are needed to pass folders from the host OS to the container OS whereas volumes are maintained by Docker and can be considered easier to backup and control by external programs. mount type=bind,source=/path/to/media,target=/media \ Using Docker command line interface: docker run -d \ Use host mode for networking in order to use DLNA. Bridge mode will be used if host mode is omitted. Is your app listening on 0.0.0.The default network mode for Docker is bridge mode. Hard to say without the info from the earlier commands. What you want is docker exec (probably docker exec -it bootup bash), which will give you a shell in the scope of the container which will let you check for your log files or try and hit the app using curl from inside the container. The other is to use the docker logs *container_name* command on a running or stopped container. There are two ways to see these- 1 is to run the container with the flag -it instead of -d to get an interactive session that will list the stdout from your container. Is there a way to tail standard output while the container is starting? Attaching after startup doesn't help me because I think by the time I run the docker attach command the app has already chokedĪ: Docker containers dump stdout/stderr to the Docker logs by default. Is there a way to see what user my app is starting up as? orĪ: Docker containers run as root unless otherwise specified. I don't know why your app isn't working, but can answer your questions.

Attaching after startup doesn't help me because I think by the time I run the docker attach command the app has already choked.Is there a way to see what user my app is starting up as? or.So I think what's happening is that my app (for some reason) doesn't have permission to create its own log file when the container starts up, and puts the app in a weird state, or even prevents it from starting up altogether.

I tried using docker attach 3f1492790397 and then hitting in my browser, to see if that would generated some standard output (my app logs both to /opt/bootup/logs/bootup.log as well as the console) but that doesn't yield any output. When I use docker exec -it 3f1492790397 bash to "ssh" into my container, I see everything looks fine, except the /opt/bootup/logs directory, which should have a bootup.log file in it - created at startup - is instead empty. My app should then be serving a simple web page at localhost:9200, so I open my browser to and I get nothing. I run docker ps: CONTAINER ID IMAGE COMMAND. I then run my container: docker run -it -p 9200:9200 -d -name bootup bootup I then build my image via: docker build -t bootup. So I created the following Dockerfile: FROM openjdk:8ĪDD build/libs/bootup.jar /opt/bootup/binĮNTRYPOINT java nfig=/opt/bootup/config -jar bootup.jar The app endpoints serve up the correct content, etc. It's very important to note that when I run my app locally on my host machine - outside of Docker - everything works perfectly fine, including the creation of log files to my host's /opt/bootup/logs directory. In the container, I want my app (a Spring Boot app under the hood) - called bootup - to have the following directory structure: /opt/īootup.log => log file GETS CREATED BY THE APP STARTUP I'm now trying to write a super-simple web service of my own and run it from inside a container. I spent the weekend pouring over the Docker docs and playing around with the toy applications and example projects.
