Https Setup Error


I hope someone can help me with this.

I have Graylog 3.1; mongodb 4; elasticsearch 6

I run graylog with docker-compose.
Graylog was running with Http.
I tried adding Https and followed the Guide for graylog 3.1

When I try to start docker-compose up I get this Error:

graylog_1        | 2020-02-07 14:27:33,809 ERROR: org.graylog2.bootstrap.CmdLineTool - Invalid configuration

My Docker-Compose.yml looks like this:

    image: graylog/graylog:3.1
      - "GRAYLOG_SERVER_JAVA_OPTS=-Xms1g -Xmx1g -XX:NewRatio=1 -server -XX:+ResizeTLAB -XX:+UseConcMarkSweepGC -XX:+CMSConcurrentMTEnabled -XX:+CMSClassUnloadingEnabled -XX:-OmitStackTraceInFastThrow"
      - GRAYLOG_HTTP_TLS_CERT_FILE=/etc/docker/certs/graylog-cert.pem
      - GRAYLOG_HTTP_TLS_KEY_FILE=/etc/docker/certs/graylog-key.pem
      - GRAYLOG_HTTP_PUBLISH_URI=https://{IPAddress}:9000/
      - GRAYLOG_HTTP_EXTERNAL_URI=https://{IPAddress}:9000/

the permissions for the files looks like this:

 drwxr-xr-x graylog docker certs
-rw-r--r-- root    root   graylog-cert.pem
drwxr-xr-x root root certs
-rwxrwxrwx root root graylog-key.pem

I tried both with root:root and with graylog:docker.

I redid the certificate and the key (the key is pkcs8):




I added graylog-cert.pem to the copied cacert.jks

I feel like I am just missing something very obvious but after spending quite some time searching I hope someone can help me with my problem.

If something else is needed I will gladly provide that.

he @Mentros

is your GRAYLOG_HTTP_TLS_* key/cert on that path you have configured available INSIDE the container?

It does not look - or you have not included that part of the docker-compose - that you have mounted the certs to the docker-image.

Please see

Hello @jan,

Thanks for the fast help.
After mounting the key/cert files in the docker-compose.yml it seems that this problem is gone.

image: graylog/graylog:3.1
- ./certs/graylog-key.pem:/etc/docker/certs/graylog-key.pem
- ./certs/graylog-cert.pem:/etc/docker/certs/graylog-cert.pem
- GRAYLOG_HTTP_TLS_CERT_FILE=/etc/docker/certs/graylog-cert.pem
- GRAYLOG_HTTP_TLS_KEY_FILE=/etc/docker/certs/graylog-key.pem

Sadly I got right into another one.
graylog_1 | Caused by: ObjectIdentifier() – data isn’t an object ID (tag = 48)
graylog_1 | at ~[?:1.8.0_232]

The solutions I found so far seem not to work for me.

  • I followed the steps for creating a sefl-signed-certificate and It “should” be the right format (the only thing that seems different is that I don’t have any bag attributes and when I list the added certificate it shows me the sha-256 and not sha1

  • I run everything on one machine so the only IP-Address in my certificate is the local machine IP-Address that I also use for all http-* lines in the docker-compose.yml

Hope I am not too much of a burden and that you could help me with this problem aswell.

I do not know what the ObjectIdentifier issue is coming from. But maybe it is related to this:

Worked it out now (somewhat).

I also had to mount the cacert.jks and I use the unencrypted key now.
Couldn’t get it to work with the encrypted key but https works fine.

Thx for the help @jan.
