Support request for Docker installed with faasd (invalid)

ikhyunAn commented 1 year ago

Why do you need this?

I cannot deploy functions anymore due to disk space running out, which I assume occurs from "snapshots" taking up space

Who is this for?

School research

Expected Behaviour

Although I have deleted all faasd functions and docker images, my function wouldn't deploy due to disk space running out. I tried to run these commands

sudo ctr --namespace openfaas-fn task delete -f $FN
sudo ctr --namespace openfaas-fn container delete $FN
sudo ctr --namespace openfaas-fn snapshot remove $FN-snapshot

but instead of successfully removing them, I got error messages such as ERRO[0000] failed to load task from [function_name]

Current Behaviour

Whenever I deploy a function, I get the error message saying:

#22 33.66 ERROR: Could not install packages due to an OSError: [Errno 28] No space left on device
#22 33.66
------
Dockerfile:39
--------------------
  37 |     COPY function/requirements.txt   .
  38 |
  39 | >>> RUN pip install -r requirements.txt --target=/home/app/python
  40 |
  41 |     WORKDIR /home/app/
--------------------
ERROR: failed to solve: process "/bin/sh -c pip install -r requirements.txt --target=/home/app/python" did not complete successfully: exit code: 1

List All Possible Solutions and Workarounds

If there's way of removing unused snapshots / docker images / caches that would be great. If not, I suggest that when 'faas-cli remove [function_name]' is run all the snapshots etc. are removed as well.

Which Solution Do You Recommend?

Hey it looks like you may have mistakenly installed Docker on faasd VM? The output that you're sharing isn't from faasd but from Docker run.

Can you explain please?

And share df -h / along with lsblk

The VM I'm using is a collaborative workspace, and the docker is installed on the VM on which faasd is also installed. I have the minio set up on the vm, the reason why docker is installed on the vm. I do see that it's recommended not to install the docker into the same host as faasd, but does the error message I'm seeing come from this problem?

I have uninstalled/deleted other packages and system files to free space, so the values on df -h are now lower than what they were. Before the /dev/vda usage was close to 100%.

faasd internal implementation already does the cleanup for task, snapshot and container, as implemented here.

You cannot have docker installed on the same host as faasd, this is probably why you're running into problems.

BuildKit can be installed and used, with faas-cli shrinkwrap followed by docker build.

openfaas / faasd
