Hej

what tutorial are you following?

4

hello, thanks for the reply ! this tutorial : http://docs.graylog.org/en/2.2/pages/installation/docker.html

/graylog/data/journal and /graylog/config from the examples in the documentation have to be existing local directories which are mounted into the Graylog Docker container.

See https://docs.docker.com/compose/compose-file/#volumes for details.

Hello thanks for the answer but can you be more verbose i’m new to docker !
where should i create this directories ? what the full path ? i went to
/user/share and created these directories but error still happenned !

You can use an arbitrary path on your host machine for these directories, they don’t have to be at /graylog/data/journal and /graylog/config.

Just make sure to mount them at the correct path inside the container, i. e. /usr/share/graylog/data/journal and /usr/share/graylog/data/config.

Please read again what I’ve written in my last post:

Additionally, I’d recommend using the virtual appliance (OVA) if you don’t want to learn Docker basics right now: http://docs.graylog.org/en/2.2/pages/installation/virtual_machine_appliances.html

ok thanks i finally understood it.

i can see the mongo and elasticsearch container running docker ps but not
graylog.

where can look to see what go wrong ?

11

You can check the logs of the Docker container: docker logs | Docker Docs

12

can’t look into the logs of a container if it didn’t started ! here what i
see

Well, you can see the error message on your screenshot:

If REST and Web interface are served on the same host/port, the protocols must be identical!

TLS (HTTPS) must be used on both listeners (Graylog REST API and Graylog web interface) if they’re running on the same network interface (port).

hello, i keep fighting to make graylog works with ssl
i generated ssl with letsencrypt. seem like letsencrypt privkey is not in
pkcs8 format so i used openssl to do the change.

any tutorial with using letsencrypt ?

See http://docs.graylog.org/en/2.2/pages/configuration/https.html for details about configuring HTTPS in Graylog.
