OH2.2 - docker-compose vs docker - does not start

martinvw · September 8, 2017, 8:25am

I have been running my openhab in dockers already for a long time but if just fails now

Version 2.1-SNAPSHOT is working fine from docker-compose.

But version 2.2-SNAPSHOT gives an error when running via docker-compose:

Compose file (it was bigger, but trimmed it down to this and still fails):

version: '2.1'

services:
  openhab:
    image: 'openhab/openhab:2.2.0-snapshot-amd64'
    network_mode: "host"

Error:

However running it with normal docker start command there is no problem at all, what am I missing…

docker run -it --name openhab --net=host openhab/openhab:2.2.0-snapshot-amd64

Thanks!

Try taking out the echo "export TERM=dumb" | tee -a ~/.bashrc from the Dockerfile, and rebuild.

@smar thanks, I tried but it does not seem to make a difference, any hint about the underlying problem you suspect?

The problem is also reported at: http://karaf.922171.n3.nabble.com/Karaf-in-Docker-td4050799.html and we recently updated Karaf (@Kai does it sound familiair to you?)

If I remove the stuff about the colors it does not give that error:

github.com

openhab/openhab-distro/blob/master/distributions/openhab/src/main/resources/userdata/etc/shell.init.script#L44


env = { shell:set $args }
edit = { shell:nano $args }
more = { shell:less -F $args }


__load_class = {
(($.reader class) classLoader) loadClass $1
}


// make sure that we catch exceptions
// as they do occur if the session is headless / non-interactive
jlineReader = $.reader
if { %(jlineReader != null) } {
setopt group
setopt auto-fresh-line
unsetopt insert-tab
keymap "^[OA" up-line-or-search
keymap "^[[A" up-line-or-search
keymap "^[OB" down-line-or-search
keymap "^[[B" down-line-or-search


}

But it still terminates:

This looks strange especially because it exits with code 0, meaning happy AFAIK and the other error is also found in particular when people state that they get that error when shutting down Karaf.

I think it may be something to do with jline and the way docker treats tty terminals. I had the same error and have now managed to work around it by (a) removing the dumb terminal environment as above and (b) adding a -t (which you already seem to have) in my docker run command.

Here’s my full docker run command, in case there is anything else in there that may be playing a part (e.g. privileged?):

docker run \
        --name openhab \
        --net=host \
        -u root \
        -e "OPENHAB_HTTP_PORT=7070" \
        -e "OPENHAB_HTTPS_PORT=8443" \
        -e "EXTRA_JAVA_OPTS=-Dgnu.io.rxtx.SerialPorts=/dev/zwave:/dev/rfx:/dev/mysensors:/dev/ttyACM0:/dev/ttyACM1:/dev/ttyUSB0:/dev/ttyUSB1:/dev/ttyUSB2" \
        --cap-add=NET_ADMIN \
        --cap-add=NET_RAW \
        -v /etc/localtime:/etc/localtime:ro \
        -v /etc/timezone:/etc/timezone:ro \
        -v /opt/openhab/conf:/openhab/conf \
        -v /opt/openhab/userdata:/openhab/userdata \
        -v /opt/openhab/addons:/openhab/addons \
        -v /opt:/opt \
        --privileged \
        -t -d  \
        --restart unless-stopped \
        openhab:latest

EDIT: Sorry, just re-read your original post and realised that you had it working with the docker run command and not the compose file. The problem you are having in the compose file is that you don’t have the -t argument. Try adding the line tty: true into your compose file.

Yes that was it!

I will create a PR to fix the example in openhab-docker later this week!

Thanks!
