Error when trying to run frappe commands on Docker install

Hi ,

I encountered the following error when trying to run the clear-cache command on a Docker install

Any ideas ?

Kind regards

Have you mounted the sites volume if you’re running the command in new container with docker run?

What is in your sites/app.txt?

Hi @revant_one

Thanks for responding. It’s an existing setup where site is already running. I just ran the command to clear cache from the terminal as shown below:

docker run \
    -v my-project_sites-vol:/home/frappe/frappe-bench/sites \
    --network webproxy \
    --user frappe \
    frappe/frappe-worker:version-13-beta bench --site clear-cache

Where is the sites/app.txt file located pls?

It’s in “my-project_sites-vol” mounted inside container at /home/frappe/frappe-bench/sites.

refer this to edit it if needed, frappe_docker/ at main · frappe/frappe_docker · GitHub

Following might be your real problem:

use frappe/erpnext-worker image instead of frappe/frappe-worker image.

Hi @revant_one

This actually solved the issue… thanks a million!
