Original GitHub issue: https://github.com/budtmo/docker-android/issues/65
I'm attempting to set the environment variable APPIUM_HOST to the hostname of the container.
I'm not sure if you're familiar with the docker image selenium/node-chrome, but there you're able to override the host and set it to the hostname of the container by doing entrypoint: bash -c 'SE_OPTS="-host $$HOSTNAME" /opt/bin/entry_point.sh'
Selenium Chrome node .yml example
chrome:
image: selenium/node-chrome:3.7.1
ports:
- "5556:5556"
depends_on:
- hub
environment:
- HUB_PORT_4444_TCP_ADDR=hub
- HUB_PORT_4444_TCP_PORT=4444
entrypoint: bash -c 'SE_OPTS="-host $$HOSTNAME" /opt/bin/entry_point.sh'
Would you happen to know how to set the APPIUM_HOST to the hostname of the container?
SamsungGalaxyS6:
image: butomo1989/docker-android-x86-7.1.1
ports:
- 6080:6080
environment:
- DEVICE=Samsung Galaxy S6
- APPIUM=True
- CONNECT_TO_GRID=True
- SELENIUM_HOST=hub
- SELENIUM_PORT=4450
entrypoint: bash -c {How to set appium_host to container hostname}
Use Case:
I'm running on a docker swarm and my reason to set the APPIUM_HOST to the container hostname is that a container can have multiple interfaces when we start appium it tries to make a guess based on the interfaces available. It then sends this address to the hub to contact it back. In case of multiple interfaces the address can be determined wrongly and the hub is not able to communicate back with the node.
To fix this issue we need to ourself determine the hostname of the container.

Hi @rlupo09 ,
could you try to pass APPIUM_HOST in environment variable to overwrite the default value?

Hi @butomo1989,
It's not a bug, but a help wanted. Yes I can override the default value with the APPIUM_HOST, but how would one get the hostname of the container to override the default value with.
@budtmo commented on GitHub (Feb 14, 2018):
Hi @rlupo09 ,
If you can try to run command "hostname -i” inside container or if you find the ip from host machine, you can pass through command “export”, e.g. https://github.com/zalando-incubator/docker-locust/blob/master/local.sh#L161-L164. I hope it helps :)
@rlupo09 commented on GitHub (Feb 15, 2018):
Thank you butomo1989. I was able to do it with hostname -i
command: bash -c 'APPIUM_HOST=$$(hostname -i) /usr/bin/supervisord --configuration supervisord.conf'
