[SOLVED] "docker run -dti" with a dumb terminal

Issue

updated: added the missing docker attach.

Hi am trying to run a docker container, with -dti. but I cannot access with a terminal set to dumb. is there a way to change this (it is currently set to xterm, even though my ssh client is dumb)

example:

create the container

docker run -dti --name test -v /my-folder alpine /bin/ash
docker attach test
apk --update add nodejs
cd /my-folder
npm install -g gulp

the last command always contains ascii escape chars to move the cursor.

I have tried "export TERM=dumb" inside the running container, but it does not work.

is there a way to "run" this using the dumb terminal?

I am running this from a script on another computer, via (dumb) ssh.

Solution

using the -t which sets this https://docs.docker.com/engine/reference/run/#env-environment-variables, however removing effects the command prompt (the prompt is not shown)

possible solution 1 remove the -t and keep the -i. To see if the command has completed echo out a known token (ENDENDEND). ie

docker run -di --name test -v /my-folder alpine /bin/ash
docker attach test
apk --update add nodejs;echo ENDENDEND
cd /my-folder;echo ENDENDEND
npm install -g gulp;echo ENDENDEND

not pretty, but it works (there is no ascii in the results)

Possible solution 2 use the journal, docker can log out to the linux journal, this can be gathered as commands are executed in the container. (I have yet to fully test this one out. however the log seems to be a nicer output of what happened)
