Actions Taken:

  • Already reset credentials.yml.enc using fly console connection;
  • Reset/Remove RAILS_SECRET_KEY
  • Generate new credentials.yml.enc

Any of this seems work properly, anyone could help me?
Thanks!

By any chance do you have a file by the name of config/credentials/production.key?

3

Thanks rubys,

I don’t have this file in VM, there’s a way to create it?

No, don’t create it. One common problem is to have two sets of credentials and use the wrong one. We’ve now ruled that out.

Rereading, I see you said:

RAILS_SECRET_KEY

That’s not the correct variable. See: Environment Configuration · Fly Docs

Enviroment variable RAILS_MASTER_KEY has already been created when I started.

Any other solution in mind?

I’ve tried follow this instructions but without success:

6

Does RAILS_MASTER_KEY have the right value?

Compare the results of

fly ssh console -C "printenv RAILS_MASTER_KEY"

… with the contents of config/master.key

7

There’s no config/master.key created on the rails fly instance.
I tried insert a docker command to created it using the printenv, but it returns permission denied
