Graylog not talking to https Elasticsearch

Hello there,
I have successfully setup graylog unsecured in a docker environment and decided to go secured and make the switch to https. Unfortunately, I’m having trouble getting Graylog to talk to Elasticsearch. According to the logs everything comes up but it can’t find my Elasticsearch container and keeps trying to connect and times out. This results in a 502 on my NGINX proxy as it can’t connect. Hopefully someone can tell me what I have setup incorrectly. Here are the logs and details of my setup.

Below is the offensive log indicating it can’t connect to Elasticsearch.

Some background about my environment: I run 4 containers via docker-compose version 1.8.0, build f3628c7. Other versions are listed below. As you can see, docker is showing unhealthy because it can’t talk to Elasticsearch.

#
# This is the Graylog configuration file. The file has to use ISO 8859-1/Latin-1 character encoding.
# Characters that cannot be directly represented in this encoding can be written using Unicode escapes
# as defined in https://docs.oracle.com/javase/specs/jls/se8/html/jls-3.html    #jls-3.3, using the \u prefix.
# For example, \u002c.
#
# * Entries are generally expected to be a single line of the form, one of the following:
#
# propertyName=propertyValue
# propertyName:propertyValue
#
# * White space that appears between the property name and property value is ignored,
#   so the following are equivalent:
#
# name=Stephen
# name = Stephen
#
# * White space at the beginning of the line is also ignored.
#
# * Lines that start with the comment characters ! or     # are ignored. Blank lines are also ignored.
#
# * The property value is generally terminated by the end of the line. White space following the
#   property value is not ignored, and is treated as part of the property value.
#
# * A property value can span several lines if each line is terminated by a backslash (‘\’) character.
#   For example:
#
# targetCities=\
#         Detroit,\
#         Chicago,\
#         Los Angeles
#
#   This is equivalent to targetCities=Detroit,Chicago,Los Angeles (white space at the beginning of lines is ignored).
#
# * The characters newline, carriage return, and tab can be inserted with characters \n, \r, and \t, respectively.
#
# * The backslash character must be escaped as a double backslash. For example:
#
# path=c:\\docs\\doc1

Hi,

maybe I missed it. Where did you configure Elasticsearch to listen to https?

And this seems wrong (graylog.conf):

These are the hosts you’re trying to connect to. You don’t start them here.

Hello, thanks for the response!

Maybe that’s my problem. I haven’t changed much of the config for elasticsearch besides that directive. Look for elasticsearch.yml and the Elasticsearch section in my docker-compose file in my original post.

As far as

elasticsearch_hosts = https://0.0.0.0:9200

I gave that a shot since it wasn’t working and the container is listening on that address. I set it back to

 https://127.0.0.1:9200

I also tried turning it off and got the same result just to the default non https address.

ERROR: org.graylog2.indexer.cluster.Cluster - Couldn't read cluster health for indices [graylog_*] (Could not connect to http://127.0.0.1:9200)	

That needs to be set for https to work correct?

Please try connecting to the host name:

http://elasticsearch:9200

That should be the known name within the network that Docker-compose creates.

Thank you so much! That fixed that error! Those elasticsearch errors are gone.

I’m still getting a 502 Bad Gateway on my proxy when I try to access the graylog site. Can you check and see if my nginx.conf looks ok and if there is anything correlated that could be wrong in my graylog.conf? After that I should be good to go. I don’t see any other errors. I really appreciate the help.

nginx | 2019/04/12 21:18:30 [error] 6#6: *2 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 10.201.68.100, server: test-graylog.mydomain.com, request: "GET / HTTP/1.1", upstream: "http://10.201.68.27:9000/", host: "test-graylog.mydomain.com"

Can you show me your actual nginx.conf?

I posted it in my original post. No worries, I’ve posted it again below.

#nginx.conf

events { }
http {

  upstream backend {
    server test-graylog.mydomain.com:9000;
    keepalive 32;
  }

  server {
    listen              80;
    listen              443 ssl;
    server_name         test-graylog.mydomain.com;
    ssl_certificate     mychain.pem;
    ssl_certificate_key mykey.pem;
    ssl_protocols       TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers         HIGH:!aNULL:!MD5;

  location / {
    proxy_pass http://backend;
     }
  }
 }
  upstream backend {
    server test-graylog.mydomain.com:9000;
    keepalive 32;
  }

How should test-graylog.mydomain.com:9000 work within the docker env? You would need graylog but nothing else.

      - GRAYLOG_WEB_ENDPOINT_URI=https://10.201.68.27:9000/api

In addition you should check that you use valid configuration parameters for the Graylog Version you run in Docker …

I see what your saying. I think part of my problem was configuring the containers to properly work with the internal docker network. I made some changes as you suggested:

I changed my nginx.conf to:

 upstream backend {
    server graylog;
    keepalive 32;
  }

I checked the graylog 3.0 params and I ‘was’ going to change the graylog_web_endpoint to:

- GRAYLOG_WEB_ENDPOINT_URI=https://graylog:9000/api

but found since I’m declaring that in the graylog.conf file I don’t really need to pass that. So I just commented it out for now. It did not change my result.

I did find something I overlooked in the logs. It struck me a bit odd as previously the error was spamming the elasticsearch container logs. This time the elasticsearch container logs were clean; this came from the graylog container logs and occurred only once. I didn’t see a successful connection afterwards so I’m not sure if it connected later? The containers seem fine and show as being up in the logs.

I’m still stuck with the same 502 bad gateway error when I try to access the graylog webpage or do a local curl. Unfortunately, nothing I changed made any difference.

 nginx | 2019/04/15 22:45:49 [error] 6#6: *80 connect() failed (111: Connection refused) while connecting to upstream, client: *myip*, server: test-graylog.twec.com, request: "GET /favicon.ico HTTP/1.1", upstream: "http://GraylogServerIP:80/favicon.ico", host: "test-graylog.twec.com", referrer: "https://test-graylog.twec.com/"

I greatly appreciate the help.

I checked the graylog 3.0 params and I ‘was’ going to change the graylog_web_endpoint to:

you did not get my point completely:

Please re-read: http://docs.graylog.org/en/3.0/pages/upgrade/graylog-3.0.html#simplified-http-interface-configuration

Thanks, I see now. These parameters are completely different than the previous version. /api is now hardcoded so I removed that where I found it. I then went down the list.

I changed:

rest_listen_uri = https://graylog:9000/api 

to

http_bind_address = https://graylog

and

rest_enable_tls = true

to

http_enable_tls = true

web and rest references to:

http_tls_cert_file = /etc/nginx/mychain.pem
http_tls_key_file = /etc/nginx/mykey.pem

commented these since https://127.0.0.1:9000 is default

web_listen_uri = https://127.0.0.1:9000/
http_bind_address = https://127.0.0.1:9000/

and

web_enable_tls = true

to

http_enable_tls = true

after those changes, I did my usual docker-compose down and docker-compose up -d and I still got the same one line error.

However, on the bright side, it seems my graylog container shows ‘healthy’ now.

So, I ‘think’ that means its working? However, I still get a 502 and can’t access the website! I did notice, a few things in my nginx config. I found the directive ‘server graylog’ like below, made it resolve to my production server graylog.mydomain.com’s IP.

  upstream backend {
    server graylog;
    keepalive 32;
  }

So, I changed it back to:

upstream backend {
    server test-graylog.mydomain.com:9000;
    keepalive 32;
  }

and added https for the proxy_pass:

   location / {
      proxy_pass https://backend;
   }

and then it tries to connect for 30 seconds but times out with an SSL handshake error and another 502.

2019/04/17 02:48:17 [error] 6#6: *7 peer closed connection in SSL handshake while SSL handshaking to upstream, client: 10.x.x.100, server: test-graylog.twec.com, request: "GET /favicon.ico HTTP/1.1", upstream: "https://10.x.x.27:9000/favicon.ico", host: "test-graylog.twec.com", referrer: "https://test-graylog.twec.com/"

I feel like I’m going in the right direction here, although I’m not sure. Is there something else I need to do to get the handshake to work? Do I have to pass an upstream header in my nginx.conf?

Thanks again guys.

Either way, that is the wrong IP address. If you’re running your container normally, you’ll never bind to the actual container IP, and if it runs in host mode, you’re binding to the localhost.

Try using 0.0.0.0:9000 here, and then restore your nginx to server graylog; in the upstream block.

I want to add in addition:

http_bind_address = 127.0.0.1:9000

        The network interface used by the Graylog HTTP interface.
        This network interface must be accessible by all Graylog nodes in the cluster and by all clients using the Graylog web interface.
        If the port is omitted, Graylog will use port 9000 by default.

no protocol - only the IP and port …

You might want to re-read the docs: http://docs.graylog.org/en/3.0/pages/configuration/server.conf.html#web-rest-api

I couldn’t get that to work. I obviosuly had this setup incorrectly somewhere before hand. Going from graylog 2.5 to version 3 and then trying to get https to work… I’ve compounded my problems. So, I’ve decided to start from scratch to try and identify where my root problem actually is step by step. I built a new server, new docker graylog stack. I’ve scrapped the custom graylog.conf… I’ll just pass parameters in the docker-compose file to keep it simple. I’m going to try and get http working correctly and go from there.

I’ve identified two problems which I think are related, I just need some help on how to fix it. I can’t get graylog working unless I set the http_external_uri to the IP of the host. Otherwise I get a blank web page. According to the docs it should be

GRAYLOG_HTTP_EXTERNAL_URI=http://127.0.0.1:9000/ 

But this is what incorrectly works in my docker-compose file.:

    - GRAYLOG_HTTP_EXTERNAL_URI=http://10.x.x.45:9000/

The 2nd issue is I did set server graylog; in my upstream to somewhat work. I get a 502 and GET spams the logs.

#New nginx.conf
 events { worker_connections 1024; }
 http {
   upstream backend {
       server graylog;
       keepalive 32;
  }
  server {
   listen 80;
  server_name graylog.domain.com;
  location / {
      proxy_pass http://backend;
   }
 }
}

Here’s the logs:

2019/04/25 20:22:11 [alert] 6#6: 1024 worker_connections are not enough

Thanks for the help.

the upstream information does not include the port.

Thanks. That was it. I tried that before but the browser cache didn’t refresh. I did a ctrl-F5 and I have http working just fine again. Now that I have that working, I’ll follow the v3.0 instructions and see if I can get https working. Thanks.

Just wanted to say thanks to everyone for all the help. I got HTTPS working. I think the main part of my issues were going from v2.5 to 3.0. The rest was the stale browser cache which foiled my troubleshooting and learning how docker works with everything. You guys really cleaned up a lot of things in v3.0 and after I got up to speed with all the documentation it was actually pretty easy. I just followed the nginx config and got a blank webpage with 200 responses, so I knew I had the proxy working, just needed graylog to start serving up secured content. After that all I had to do was add this in my docker-compose and it came up.

graylog_http_enable_tls=true

Thanks guys, keep up the great work. :smiley:
