I cannot get the plugin to work with GoCD server 17.5.0 and plugin version 1.1.4.

What's the output of docker service ls -q | xargs -I ID docker service inspect ID?

[ketan]

Also the version of docker you are on.

[ketan]

Note to self:

Suspicion is that this line throws up because service.spec() likely returns a null.

[chatelain-io]

there is no service agent running, I have the same error when the plugin try to create the service.

That makes no sense. The line that's throwing the exception is this, since the line is in a loop, it very clearly implies that there is at least one service that docker.listServices (aka docker service ls) has returned.

Maybe there's a service that pops up and disappears quickly and does not show up in docker service ls; but shows up when the plugin repetitively does the equivalent.

If you add a log statement as the first line in the same loop to print the following and deploy the jar, it might help us debug and put a better fix in.

LOG.info("Service id" + service.id());
LOG.info("Service spec" + service.spec());
LOG.info("Service spec labels" + service.spec().labels());

[chatelain-io]

this is the error I get on agent creation:

I have an other issue where the log file for the plugin is not created. All the other plugin logs works, but for this on I cannot get it work

[chatelain-io]

I got it working on a fresh install of gocd server... but can't figure out why it doesn't work on our server.

[remy-tiitre]

I have the same exception with custom GoCD docker container (I run GoCD Server inside docker container). So there might be some incorrect setup from my part, but the exception seems to be exactly the same. Plugin is 1.1.4, GoCD is 17.8.0 and docker is inside the container and on the host 17.06.1-ce, /var/run/docker.sock has been mapped to GoCD container. I tried to start the GoCD with docker-compose and as service in Swarm. This exception happened on both cases.

[bdpiprava]

@remy-tiitre --- This is not reproducible at our end. I am closing the issue. Feel free to reopen this issue if you are facing this issue consistently.

[remy-tiitre]

Can you make the guide how to setup this plugin with GoCD and its agents inside docker containers. For example, do you need to have to docker client installed inside the container, or its enough to map the /var/run/docker.sock from the host, etc

[remy-tiitre]

Still get the exception when running GoCD server in docker container in a swarm mode:

The error appears in a log during the startup. And I can't save settings for the plugin, it will fail and the exception in the log is:

Java::JavaLang::RuntimeException (Interaction with plugin with id 'cd.go.contrib.elastic-agent.docker-swarm' implementing 'elastic-agent' extension failed while reques

[bdpiprava]

@remy-tiitre --- Please can you provide you plugin-settings and elastic profile for the plugin with sensitive information redacted.

[remy-tiitre]

These exceptions occure even when I have only docker-swarm-elastic-agents added to stock plugins and there is no elastic profile created.

[ketan]

These exceptions occure even when I have only docker-swarm-elastic-agents added to stock plugins and there is no elastic profile created.

The NullPointerException in DockerClientFactory seems to indicate that the plugin is not configured. I've opened #36 to fix this particular issue.

Once you configure the plugin, that exception should go away. If you're seeing a different exception than the one in the stack trace in this comment (https://github.com/gocd-contrib/docker-swarm-elastic-agents/issues/28#issuecomment-330496931), please provide that stacktrace.

[bdpiprava]

@ketan This is already fixed here. I am making new release of plugin.

[ketan]

I don't see the exception being caught and logged differently. This will merely change the NPE to a different exception. Can we catch that exception here ( https://github.com/gocd-contrib/docker-swarm-elastic-agents/blob/master/src/main/java/cd/go/contrib/elasticagents/dockerswarm/elasticagent/DockerPlugin.java#L83) and log it differently

I don't see any point in handling that PluginSettingsNotConfiguredException differently because on that exception plugin sendsPlugin settings is not configured. error message to server.

@ketan WDYT ?

I don't agree, this exception will be bubbled and printed along with a stacktrace. I'm more concerned about the fact that a stacktrace seems to indicate there's an error, when in reality it's not an error, certainly not something that should go un-handled.

[remy-tiitre]

After saving plugin settings I get into log these rows:

It might be something related to GoCD server setup, as when the server starts up, it gives me the following rows:

But building still doesnt work and it seems that the logging is broken as well. In GoCD log I get the following exception when I start pipeline that has elastic agent applied:

[ketan]

What did you pass in as the memory limits? It looks like parsing that has failed. We have a fix for this issue in the upcoming release. We recommend setting the size using using a an integer and a unit. (512mb, 2gb, etc...)

[remy-tiitre]

As you can see from the sample profile, I left them empty to make the profile as simple as possible. It doesn't say anywhere that they are mandatory. But this seems to have fixed the elastic agent part. It still doesn't work correctly. I get the following errors in my log:

@remy-tiitre --- server don't know much about plugin configuration. iIt is plugins job to validate the profile. When you create a profile from config.xml server will not ask plugin to validate the profile as it is expensive(depends on plugin) call and it might block config save.

Please use Elastic Profile API or configure the profile through UI: Admin > Elastic Agent Profiles

I created the Elastic Agent Profile from Admin > Elastic Agent Profiles page and it did not complain about memory settings missing. And That page has only "Docker image:*" marked as mandatory. But it seems that adding memory limist fixed this issue and this task can me closed.
