[graylog2] SMTP configuration in graylog2/server docker container

[Hannes Diedrich]

Hello!

I have problems configuring the STMP settings (or any settings) in my
graylog docker container.

This is the setup:
CentOS Linux release 7.2.1511 (Core)
Docker version 1.10.3, build cb079f6-unsupported

I installed graylog after the instruction on
http://docs.graylog.org/en/2.1/pages/installation/docker.html :


*docker run --name some-mongo -d mongo:3*


*docker run --name some-elasticsearch -d elasticsearch:2 elasticsearch -Des.cluster.name="graylog"*

*docker run --link some-mongo:mongo --name graylog --link some-elasticsearch:elasticsearch -p 9000:9000 -p 12201:12201/udp -e GRAYLOG_PASSWORD_SECRET=$SECRET -e GRAYLOG_ROOT_PASSWORD_SHA2=$PASSWORD -e GRAYLOG_WEB_ENDPOINT_URI="http://<ip>:9000/api" -d graylog2/server*
For the first tests it worked fine, although there is a notification:

*The configuration for the email transport subsystem has shown to be missing or invalid. Please check the related section of your Graylog server configuration file. This is the detailed error message: Email transport is not enabled in server configuration file!*
Consequently, the sending of a test alert failed.

So I tried multiple ways of configure the server:

1.Created /etc/graylog/server/server.conf using the example in /usr/share/graylog/data/config (although /etc/graylog is already missing in the container)
and changed the following settings:








*transport_email_enabled = truetransport_email_hostname = <hostname>transport_email_port = 587transport_email_use_auth = truetransport_email_use_tls = truetransport_email_use_ssl = truetransport_email_auth_username = <email-adress>transport_email_auth_password = <secret>*

2. Configured graylog via the keywords at docker run:





*docker run --link some-mongo:mongo --name graylog --link some-elasticsearch:elasticsearch -p 9000:9000 -p 12201:12201/udp -e GRAYLOG_PASSWORD_SECRET=$SECRET -e GRAYLOG_ROOT_PASSWORD_SHA2=$PASSWORD -e GRAYLOG_WEB_ENDPOINT_URI="http://<ip>:9000/api" -e GRAYLOG_TRANSPORT_EMAIL_HOSTNAME=<url> -e GRAYLOG_TRANSPORT_EMAIL_USE_TLS="true" -e GRAYLOG_TRANSPORT_EMAIL_USE_SSL="true" -e GRAYLOG_TRANSPORT_EMAIL_USE_AUTH="true" -e GRAYLOG_TRANSPORT_EMAIL_PORT=587 -e GRAYLOG_TRANSPORT_EMAIL_AUTH_USERNAME=<email-adress>-e GRAYLOG_TRANSPORT_EMAIL_AUTH_PASSWORD=<secret> -e GRAYLOG_TRANSPORT_EMAIL_ENABLED="true" -e GRAYLOG_TIMEZONE=Europe/Berlin -d graylog2/server*

Tried this way also:

*docker run --link some-mongo:mongo --name graylog --link some-elasticsearch:elasticsearch -p 9000:9000 -p 12201:12201/udp -e GRAYLOG_PASSWORD_SECRET=$SECRET -e GRAYLOG_ROOT_PASSWORD_SHA2=$PASSWORD -e GRAYLOG_WEB_ENDPOINT_URI="http://<ip>:9000/api" -e GRAYLOG_SMTP_SERVER="<hostname> --port=587 --user=<email-adress> --password=<secret>" -d graylog2/serve*r

But none of them had impact (although the server started)

3. Installing docker-compose in order to create the three containers from scratch did not work because our python system packages conflict with docker-compose dependencies.


What have I done wrong? Did I miss anything? Any comment is very welcome!
Thanks in advance!
