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

```bash
cd /var/discourse
git pull

```

then find the default image tag the launcher is using:

```bash
grep -m1 '^image=' launcher

```

the output should look like:

```plaintext
image="discourse/base:2.0.20260915-0028"

```

then run:

```bash
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…
