5.1.1: Plugin installation behind Proxy

dawiro · January 3, 2017, 3:38pm

Hi,
I'm finding that plugin installation is failing from behind proxy. This has me wondering how proxying should be configured in the current version. Neither of these approaches are working for me:

# export HTTP_PROXY=http://<proxy_host>:<proxy_port>
# export HTTPS_PROXY=https://<proxy_host>:<proxy_port>
# /usr/share/logstash/bin/logstash-plugin install logstash-filter-zeromq

...or add jvm args to jam.options:

-DproxyHost=<proxy_host>
-DproxyPort=<proxy_port>

Neither works, generating this output instead:

ERROR: Something went wrong when installing logstash-input-zeromq, message: Connection refused - Connection refused

However, if I test internet connectivity from the command-line it works:

# wget --spider http://example.com
Spider mode enabled. Check if remote file exists.
--2017-01-03 15:05:18--  http://example.com/

Would appreciate feedback/help here...

Please format your code with the </> button, it’s very hard to read otherwise.

Ok, done that...

I am encountering the same issue here in a docker container where the entrypoint script ensures that certain plugins are installed prior to starting elasticsearch. This used to work end of November and now fails. As I am using the same version of Elasticsearch, I assume that it is not a change in the logstash-plugin code but something in the plugin repository changed which breaks our proxy connection.

Sandro_Scanu · January 4, 2017, 12:21pm

Same issue here, just looking for the plugins to download an install it with bin/logstash-plugin install --local {plugin} but cannot find the plugins.
I'm also behind a proxy. bin/logstash-plugin list works...

Roland_L · January 5, 2017, 12:22pm

Same problem here. I'm using Logstash 5.1.1 and have set the proxy according to: https://www.elastic.co/guide/en/logstash/current/working-with-plugins.html#proxy-plugins:

root@server:/usr/share/logstash/bin# echo $http_proxy
http://proxy.host:3128
root@server:/usr/share/logstash/bin# echo $https_proxy
http://proxy.host:3128
root@server:/usr/share/logstash/bin# echo $HTTP_PROXY
http://proxy.host:3128
root@server:/usr/share/logstash/bin# echo $HTTPS_PROXY
http://proxy.host:3128

Trying to install the "multiline" plugin and I get a Connection refused:

root@server:/usr/share/logstash/bin# DEBUG=1 ./logstash-plugin install logstash-filter-multiline
DEBUG: exec /usr/share/logstash/vendor/jruby/bin/jruby --1.9 /usr/share/logstash/lib/pluginmanager/main.rb install logstash-filter-multiline

It seems that logstash-plugin is simply ignoring the proxy.

jott · January 6, 2017, 3:01pm

I accidentally installed the latest logstash version instead of the intended version. When I fixed that (thus reverting to 5.0.1), the plugin installation works again. I also had to set not only HTTP_PROXY but also HTTPS_PROXY for all plugins to succeed.

This looks like a regression to me (as it worked in 5.1.1) but I am not deep enough into logstash to determine whether this is due to plugin-install or the bundled jruby version.

warkolm · January 6, 2017, 11:10pm

See https://github.com/elastic/logstash/issues/6044 for the problem and some suggested workarounds.

This will be fixed in 5.2 though!

Roland_L · January 9, 2017, 8:17am

Thanks @warkolm! At least the download seems to work now, using:

export JRUBY_OPTS="-J-Dhttp.proxyHost=proxy.host -J-Dhttp.proxyPort=3128

Unfortunately I get a different error this time:

root@server:/usr/share/logstash/bin# ./logstash-plugin install logstash-filter-multiline
Validating logstash-filter-multiline

Error Bundler::InstallError, retrying 1/10
An error occurred while installing logstash-core-event-java (5.1.1), and Bundler cannot continue.
Make sure that `gem install logstash-core-event-java -v '5.1.1'` succeeds before bundling.
WARNING: SSLSocket#session= is not supported
^Croot@server:/usr/share/logstash/bin#

And if I try to use the suggested command, I get:

root@server:/usr/share/logstash/bin# gem install logstash-core-event-java -v '5.1.1'
ERROR:  Could not find a valid gem 'logstash-core-event-java' (= 5.1.1) in any repository

Hi,
I finally solved this issue!! i hope it helps you

remove and re-install logstash-5.1.1 (start with pure package)
use follow script

gist.github.com

https://gist.github.com/devlatte/fda1c57ed7a33daea73c8b00799d74a1

logstash5_1_1_plugin_install.sh

//from pure package
export http_proxy="proxy.host:3128"
export https_proxy=$http_proxy

export JRUBY_OPTS="-J-Dhttp.proxyHost=proxy.host -J-Dhttp.proxyPort=3128"
DEBUG=1 JARS_SKIP='true' bin/logstash-plugin install logstash-filter-json_encode

Roland_L · January 11, 2017, 10:25am

Thanks! That works!

So it seems the only thing I was missing was JARS_SKIP='true' - whatever that means...

Conclusion for 5.1.1:

you have to set the JRUBY_OPTS for logstah-plugin to use the proxy
you have to set http_proxy and https_proxy for Ruby Gem (which is apparently called by logstash-plugin)
and you have to set JARS_SKIP='true' also (for Ruby Gem?) for the installation to work

What a mess...

dawiro · February 7, 2017, 12:13pm

Can I have a definitive statement on the fix for this please? I've upgraded to 5.2.0 and i still cannot install plugins. And, the above workaround fails too:

# bin/logstash-plugin install logstash-filter-de_dot
Validating logstash-filter-de_dot
Installing logstash-filter-de_dot
Error Bundler::InstallError, retrying 1/10
An error occurred while installing logstash-core-event-java (5.2.0), and Bundler cannot continue.
Make sure that `gem install logstash-core-event-java -v '5.2.0'` succeeds before bundling.
