adding a host to the docker command

[angel.m...@gmail.com]

Hi, 

I've got a docker container that needs to access a particular port on the host machine. It  looks like I need to be able to set this up as part of the command.json but it's not clear to me where I can put it. 

If I was running the docker container directly the command would look something like this.

docker run --add-host="app-backend:10.15.1.24" my-app  

Is there a way of getting this into the json command for launch from xnat?

thanks

Angel

Hi Angel,

The --add-host flag is not supported in the XNAT Container Service command structure.  Containers running under Container Service do have a few environment variables set by default, including XNAT_HOST.

Using this env var, or any other input you supply to the command, you could append the /etc/hosts file as part of your container's run script. e.g. 

      > echo $XNAT_HOST app-backend >> /etc/host

at container startup.

Best,

Matt
