Login problem with GrayLog after installation - Docker Compose

[osvaldofilho]

Hi,

I try to install GrayLog 3.2 in a different way - using docker (docker compose). All containers are up. I’ve tried to use env_file to put my pass in another file, but it didn’t work. Also, I tried with GRAYLOG_PASSWORD_SECRET. I put my own pass and then I run the command echo -n “mypass” | sha256sum and put the result on GRAYLOG_ROOT_PASSWORD_SHA2. The command docker-compose up run without erros, but I recieve the message at the login screen: Invalid credentials, please verify them and retry.
I need any extra configuration or field to make it work?

Hello @osvaldofilho!

This documentation should help.

https://docs.graylog.org/en/3.3/pages/getting_started/configure.html

I think maybe your steps are out of order.

1. Generate a password secret
   pwgen -N 1 -s 96
2. Place that secret in the configuration for password_secret (GRAYLOG_PASSWORD_SECRET)
3. Pick an admin password. (e.g. hunter2)
4. Hash that password using the command
   echo -n "Enter Password: " && head -1 </dev/stdin | tr -d '\n' | sha256sum | cut -d" " -f1
5. Place the password hash (from step 4) in the configuration for root_password_sha2 (GRAYLOG_ROOT_PASSWORD_SHA2)
6. Log in with username admin and the non-hashed password (from step 3)

Let us know if that works!

Thanks! My problem was the pwgen command. It works!
