2 years ago Hi. I am new to MDSPlus and am trying to use your docker containers to try it out. When going through your demo commands, I get a failure when trying to run demo-mdstcl:
dan@dan-desktop:~/Desktop/DockerizedMDSplus/demo$ UID=$(id -u) GID=$(id -g) docker-compose up -d bash: UID: readonly variable WARNING: The UID variable is not set. Defaulting to a blank string.

On my system I'm 1000:1000, would this cause any issue?
I'm looking to get experience in just understanding MDSplus, what it is, what pieces there are and how they work together, etc. Thanks.
Had these same problems.
1) The start script has a conditional statement looking for the '$DIR' to be opening. I changed it to point to the $PWD I'm in and the demo runs. However, the default config is python 2 in this Alpine container. :-( I'm working out an Ubuntu18 image to run with python3.6. But ran into new problems. Yay.
Here's what I changed to to get it running:
if [[ "$0" == "" ]]; then
DIR=$(realpath "$(dirname $BASH_SOURCE)/")
else
# DIR=$(realpath "$(dirname $0)/")
DIR="./"
fi
DEMO_PATH="/home/controls/DockerizedMDSplus/demo"
NETWORK=demo_default
# DOCKER_FLAGS="--network=$NETWORK --env-file=$DIR/config.env --volume=$DIR/scripts:/scripts --volume=$DIR/pydevices:/pydevices"
DOCKER_FLAGS="--network=$NETWORK --env-file=config.env --volume=${DEMO_PATH}/scripts:/scripts --volume=${DEMO_PATH}/pydevices:/pydevices"
...
...
...2) In the compose file, change the stanza:
UID=${UID}
GID=${GID}to
UID=${uid}
GID=${gid}and instead of the given up command preface, preface with
uid=${id -u} gid=${id -g} docker-compose ...This way, you don't get the READ ONLY error. I'm in a similar boat too, trying to understand MDSplus. And tbh, a lot of it is underwhelmingly under documented or out of date: see EPICS interface.
Now, see my next post for the trouble I'm in...
I hope that helped.
