Hmmm, this is really weird. We calculate the size of db_shared_buffers here: discourse-setup master echo echo "Insufficient disk space may result in problems running your site, and" echo "may not even allow Discourse installation to complete successfully." echo echo "Please free up some space, or expand your disk, before continuing." echo echo "Run \`apt-get autoremove && apt-get autoclean\` to clean up unused" echo "packages and \`./launcher cleanup\` to remove stale Docker containers." exit 1 fi } ## ## If we have lots of RAM or lots of CPUs, bump up the defaults to scale better ## scale_ram_and_cpu() { local changelog=/tmp/changelog.$PPID I can’t see how you end up with just 8kB following this. Can you check your app.yml file for the value?

Sure thing, where is app.yml located, or what command should I execute to view it (cat)?

/var/discourse/containers/app.yml I found nano Easier to use.

Thank you, give me a second while I change it.

My post disappeared because it got caught in a spam filter, anyways I’ll paste the new log on pastebin. https://pastebin.com/UtuVLWtF

after you made changes to the yml file, run this command. ./launcher rebuild app
