Error rebuilding - Cannot start container - connection reset by peer

Support

Today I couldn’t update a discourse which was 13 commits behind. (The other three I manage upgraded just fine)

The relevant error seems to be:

uglifyjs ‘/var/www/discourse/public/assets/_application-1d81ebab3894f7cd324e3d95bb43a89d.js’ -p relative -c -m -o ‘/var/www/discourse/public/assets/application-1d81ebab3894f7cd324e3d95bb43a89d.js’ --source-map-root ‘/assets’ --source-map ‘/var/www/discourse/public/assets/application-1d81ebab3894f7cd324e3d95bb43a89d.js.map’ --source-map-url ‘/assets/application-1d81ebab3894f7cd324e3d95bb43a89d.js.map’

Anyone run into this before?

trying a second time also failed

Rebooting the host resulted in the same error

A plugin? Try disabling all custom plugins.

If you’re in a hurry and have nothing else to try, try adding this to your Yaml file (note the empty space between single quotes:

DOCKER_FIX: '                                        '

Stolen from here.

Didn’t think to post that… there is only one enabled (there is a theme which has been disabled for a long time)

     - mkdir -p plugins
      - git clone https://github.com/discourse/docker_manager.git

Try @omfg’s recommendation in ENV, it may fix it … this is one crazy docker bug.

@sam agreed… that’s one interesting bug.

I put that bit in the first line after ENV and @omfg that worked!
