Which command only updates the Docker image?

hmmm, only way i know is to first update the launcher script:

cd /var/discourse
git pull

then find the default image tag the launcher is using:

grep -m1 '^image=' launcher

the output should look like:

image="discourse/base:2.0.20260915-0028"

then run:

docker pull discourse/base:2.0.20260915-0028

then when you run ./launcher rebuild app it should skip the download i think.

it should say Status: Image is up to date for discourse/base:2.0.20260915-0028 when you run the rebuild…
