** FAILED TO BOOTSTRAP ** please scroll up and look for earlier error messages, there may be more than one.
./discourse-doctor may help diagnose the problem.

it looks like the main error is that it cannot connect to the server, but I don’t quite understand it…

Could someone help?

How much RAM memory do you have in this server?

3

1 gb.

Hmmm, this is really weird.

We calculate the size of db_shared_buffers here:

https://github.com/discourse/discourse_docker/blob/master/discourse-setup#L226-L245

I can’t see how you end up with just 8kB following this.

Can you check your app.yml file for the value?

6

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

7

/var/discourse/containers/app.yml

I found nano Easier to use.

that should not be zero

change it to

db_shared_buffers: “128MB”

10

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.

12

after you made changes to the yml file, run this command.

./launcher rebuild app

13

Thank you, it also returns a failed to bootstrap error, see the log:

14

its having some issues with shared_buffers and postgresql.

what else is running on that instance ?

15

Nothing else is running on the vm (i think)…
I bought it from Azure
