Cannot update HA in docker

Hi,

I am currently running HA 0.85.0b0 inside a docker container on a raspberry pi 3.
Today I tried to update it using the following command :
sudo docker pull homeassistant/raspberrypi3-homeassistant:latest

After a couple of minutes, I always see the process being stopped with an error on extracting one ‘package’ :

On other occasion, I have seen these messages :

  • failed to register layer: Error processing tar file(exit status 1): open /usr/local/lib/python3.6/site-packages/xlsxwriter/pycache/styles.cpython-36.pyc: no space left on device
  • could not get decompression stream: fork/exec /usr/bin/unpigz: cannot allocate memory

Has anyone ever seen these types of error while updating a docker container ?

Looks like your SD card is full.
Should be able to confirm with
df -h /

When you update you will need to delete the old docker images or you’ll just end up with a full SD card. You can see by the ‘… already exists’ messages you have a lot of them.

Thanks for the replies.
I forgot to mention that the SD card is not full :
$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/root 15G 9.0G 5.0G 65% /
devtmpfs 466M 0 466M 0% /dev
tmpfs 470M 0 470M 0% /dev/shm
tmpfs 470M 13M 458M 3% /run

tmpfs 470M 0 470M 0% /sys/fs/cgroup
/dev/mmcblk0p1 42M 23M 20M 54% /boot

I assumed I could pull the latest image while keeping HA running with the old image and then just do a restart when the new image is ready. Is that not possible ? Do I really have to delete the current image ?

I cleaned old docker images with “docker system prune -a”.
After that, the docker pull command worked fine and I now have 0.86.4 running on my Raspberry Pi.

Thanks for the help.

I am gain seeing the same kind of error while trying to update my docker HA image to 0.88. The difference is that this time the error is consistent and always about decompression stream and unpigz :

I have tried stopping the container and cleaning with prune -a but it seems to not be enough this time.

Here is my disk space :

Filesystem      Size  Used Avail Use% Mounted on
/dev/root        15G  6.4G  7.6G  46% /
devtmpfs        466M     0  466M   0% /dev

/dev/mmcblk0p1   42M   23M   20M  54% /boot

Did you expand the file system storage?
If not, that could be the problem. It’s a thing that costs you like 10 seconds to do.
