XWiki on Docker behind Proxy ignores JAVA_OPTS

cd-zbfs · July 14, 2020, 6:05am

Hi,

I try to get a XWiki demo on our docker host up and running. I used the following docker-compose.yml.
As you can see we have a corporate proxy which has to be set to access the internet.

version: '2'
networks:
  bridge:
    driver: bridge
services:
  web:
    image: "xwiki:stable-mysql-tomcat"
    container_name: xwiki-web
    depends_on:
      - db
    ports:
      - "8082:8080"
    environment:
      - XWIKI_VERSION=xwiki
      - DB_USER=xwiki
      - DB_PASSWORD=xwiki
      - DB_DATABASE=xwiki
      - DB_HOST=xwiki-db
      - JAVA_OPTS="-Dhttp.proxyHost=10.x.x.x -Dhttp.proxyPort=80 -Dhttps.proxyHost=10.x.x.x -Dhttps.proxyPort=80"
    volumes:
      - xwiki-data:/usr/local/xwiki
    networks:
      - bridge
  db:
    image: "mysql:5.7"
    container_name: xwiki-db
    volumes:
      - ./12/mysql-tomcat/mysql/xwiki.cnf:/etc/mysql/conf.d/xwiki.cnf
      - mysql-data:/var/lib/mysql
    environment:
      - MYSQL_ROOT_PASSWORD=xwiki
      - MYSQL_USER=xwiki
      - MYSQL_PASSWORD=xwiki
      - MYSQL_DATABASE=xwiki
    networks:
      - bridge
volumes:
  mysql-data: {}
  xwiki-data: {}

I get the setup wizard and can add a admin account but in the second step the list of flavors remains empty.

I see the proxy is set via JAVA_OPTS in the container startup logs

A curl with the same proxy set can load the webpage just fine.

Did I miss anything? Is there anything else I have to set to get xwiki on docker to use the proxy?

thanks
cd

jwielsch · July 15, 2020, 10:20am

Hey, you put the http and the https proxy port to 80. is that correct? perhaps it should be 80 and 443?! just guessing.

Regards.

EDIT

I have never set any proxy ports - and xwiki runs just fine with haproxy.

my java_opts:

JAVA_OPTS=“-Xmx2048m -Djava.awt.headless=true”

EDIT 2

Welcome to the community

cd-zbfs · July 15, 2020, 10:36am

Hi,

this is not a reverse proxy like HAProxy but a corporate proxy from the client (or in this case server) to the internet.
I checked and both (http and https) protocols are proxyed over port 80 so this checks out.
Also there is no SSL Inspection active on the proxy.

My problem is as far as I can tell (tcpdump and error logs) the proxy setting via JAVA_OPTS is not honored by xwiki or at least not by the setup wizard.

I got the JAVA_OPTS settings hint from here https://www.xwiki.org/xwiki/bin/view/Documentation/AdminGuide/Installation/#HRunningXWikibehindaproxyserver
I’m wondering if this is outdated information or if it does not work with the docker image.

Thanks for the welcome.
cd

jwielsch · July 15, 2020, 11:01am

ok, my fault. Sorry.

Perhaps you should give this a try:

on Set up HTTP Proxy for Tomcat Web server - Server Fault there is an entry which says:

To get tomcat running inside my docker container I used the following settings:
JAVA_OPTS=-Dhttps.proxyHost=PROXYHOST -Dhttps.proxyPort=PROXYPORT -DproxySet=true -DproxyHost=PROXYHOST -DproxyPort=PROXYPORT

Perhaps it runs with

-DproxySet=true

But: just guessing

cd-zbfs · July 15, 2020, 2:20pm

Hi,

thanks for the link. I tried it with
- JAVA_OPTS="-Dhttp.proxyHost=10.x.x.x -Dhttp.proxyPort=80 -Dhttps.proxyHost=10.x.x.x -Dhttps.proxyPort=80 -Dhttp.proxySet=true"

docker-compose rm -f -s -v
docker volume rm docker-xwiki_xwiki-data  docker-xwiki_mysql-data
docker-compose up

Thexwiki startup log also shows the changed JAVA_OPTS

What about setting environment variables to the container?

When you build the image, or using the --env flag when you create or run the container, you can set one or more of the following variables to the appropriate value. This method makes the image less portable, so if you have Docker 17.07 or higher, you should configure the Docker client instead.

Variable	Dockerfile example	`docker run` Example
`HTTP_PROXY`	`ENV HTTP_PROXY "http://127.0.0.1:3001"`	`--env HTTP_PROXY="http://127.0.0.1:3001"`
`HTTPS_PROXY`	`ENV HTTPS_PROXY "https://127.0.0.1:3001"`	`--env HTTPS_PROXY="https://127.0.0.1:3001"`
`FTP_PROXY`	`ENV FTP_PROXY "ftp://127.0.0.1:3001"`	`--env FTP_PROXY="ftp://127.0.0.1:3001"`
`NO_PROXY`	`ENV NO_PROXY "*.test.example.com,.example2.com"`	`--env NO_PROXY="*.test.example.com,.example2.com"`

Hi,

I tried the setting the proxy via docker client config.

$ cat ~/.docker/config.json
{
 "proxies":
 {
   "default":
   {
     "httpProxy": "http://10.x.x.x:80",
     "httpsProxy": "http://10.x.x.x:80",
     "noProxy": "localhost,172.0.0.0/8"
   }
 }
}

docker inspect shows the active ENV variables. I don’t know why they are doubled but it does not work. But it does not change anything on a fresh install. tcpdump shows direct connections irgnoring the proxy. the docker container log shows the same timeout errors.
A doku-wiki and kanboard test docker container on the same system with the same proxy ENV config works and I can load extensions etc from within the webapps via the proxy.

$ docker inspect xwiki-web
[...]

I’m beginning to suspect xwiki behind a corporate proxy is a no-go.

so just for me to understand: another docker container on the same host is able to communicate through the proxy. but the xwiki-container can not?

Hi,

Yes.
There is a bitnami/dokuwiki:0-debian-10 based dokuwiki and a kanboard/kanboard:latest based kanboard installation running on the same host.

Both are PHP Webapps and both have proxy settings active in the config files (and the docker client proxy settings in the ENV section). In both cases the features that require a proxy work.
The dokuwiki for example allows the installation of extensions from the admin menu. (like xwiki the falvors).

thanks for the information.

this is strange. at the latest, if the proxy is entered in the docker, all containers with bridge configuration should use it. therefore the entry as ENV in docker-compose.yaml should be unnecessary.

can you recreate the containers without the proxy-settings in the yaml? i have no test-environment here so i cannot try to reproduce your problem. sorry.

Hi,

just recreated the container without the JAVA_OPTS setting in the docker-compose.yml.
Proxy settings in ~/.docker/config.json was kept as before.

docker inspect shows a changed “Config”: “Env” without the JAVA_OPTS but still the http[s]_proxy settings.

But no luck, I again see the direct connections from the host to xwiki.org subdomains in tcpdump and the flavor list still is empty.

Hi,

I’m an idiot…

In https://www.xwiki.org/xwiki/bin/view/Documentation/AdminGuide/Installation/#HDebuggingproxyconfigurationissues there is an example groovy(?) code to list the proxy settings in the wiki.

For
- JAVA_OPTS="-Dhttp.proxyHost=10.x.x.x -Dhttp.proxyPort=80 -Dhttps.proxyHost=10.x.x.x -Dhttps.proxyPort=80"

this shows
[…]
Name: http.proxyHost = Value 10.x.x.x -Dhttp.proxyPort=80 -Dhttps.proxyHost=10.x.x.x -Dhttps.proxyPort=80 -Dhttp.proxySet=true
[…]

which doesn’t look right.

With
- JAVA_OPTS=-Dhttp.proxyHost=10.x.x.x -Dhttp.proxyPort=80 -Dhttps.proxyHost=10.x.x.x -Dhttps.proxyPort=80

(note the missing “”) it shows

[...]
Name: http.proxyHost = Value 10.x.x.x
Name: http.proxyPort = Value 80
[..]

and the flavor list in the installer shows a list of flavors. Installation works to.

So yeah my problem is solved.

One more thing, xwiki-platform/xwiki-platform-core/xwiki-platform-oldcore/src/main/java/com/xpn/xwiki/XWiki.java at 458d4d89e4f91082549676c0182b61a1526b5281 · xwiki/xwiki-platform · GitHub shows the usage of String proxyHost = System.getProperty(“http.proxyHost”); but I couldn’t find any mentioning of https.proxyHost (with the s) anywhere in the code for xwiki. Fortunately we have one proxy for http and https on the same ip and port. I don’t know what happens if you need a different proxy ip/port for https urls. Maybe someone from the xwiki devs could have a look at this.

Will give xwiki a test drive now. Thanks for the help.
