Gatling not providing port? #38

IdahoEv · 2017-01-21T01:24:37Z

I have my endpoint config set up as described in the README. When I attempt a deploy, I get an error that the port is nil:

The database for Tracker.Repo has already been created

01:18:12.463 [info]  Already up
01:18:12.600 [info] Application tracker exited: Tracker.start(:normal, []) returned an error: shutdown: failed to start child: Tracker.Endpoint
    ** (EXIT) shutdown: failed to start child: Phoenix.Endpoint.Server
        ** (EXIT) an exception was raised:
            ** (RuntimeError) server can't start because :port in config is nil, please use a valid port number

                (stdlib) proc_lib.erl:247: :proc_lib.init_p_do_apply/3

Since the only thing the docs say about the port setting is "Gatling will set this for you automatically" I'm not sure what to look at next. Thanks or any help.

Environment: DigitalOcean server Ubuntu 16.04, nothing else on it but elixir, nginx, and postgresql. I followed the instructions in this blog post as closely as possible.

Hi Evan, thanks for the feedback!

What does your /etc/init.d/tracker file on the server contain?

Can you open up iex on the server and execute these four lines from the Utilities.available_port/0 function manually? What do you get?

IdahoEv · 2017-01-22T01:28:21Z

@dennisreimann Thanks for the quick reply!

The /etc/init.d/tracker and /etc/nginx/sites-enabled/tracker files both contain the port number, see below. I've been able to get the site up by inspecting them to get the port number and then running the release directly (PORT=39491 sudo --preserve-env _build/prod/rel/tracker/bin/tracker start). I just can't do it by running mix gatling.deploy: that's what results in the above error.

Will try executing those lines manually and post a follow-up.

/etc/init.d/tracker:

I have to provide a port at the command line to load the app in iex (else I get the same error as above) but once I do the function you linked seems to be able to identify a port just fine:

~/tracker$ PORT=39492 iex -S mix
Erlang/OTP 19 [erts-8.2] [source-fbd2db2] [64-bit] [async-threads:10] [hipe] [kernel-poll:false]

IdahoEv · 2017-01-22T01:57:32Z

I'm going to add an issue about the other problem I'm having, in case it's related.

dennisreimann · 2017-01-22T10:11:16Z

I didn't mean to boot up the app with iex. Just start a normal iex session without any params outside the project folder and see whether or not getting the port number works :)

IdahoEv · 2017-01-22T16:47:31Z

The reason I booted the app is that (ashamed to admit this) I didn't otherwise know how to load an external library in an iex session. This morning I figured it out, though, so here you go:

deploy@my-app:~$ iex
Erlang/OTP 19 [erts-8.2] [source-fbd2db2] [64-bit] [async-threads:10] [hipe] [kernel-poll:false]

Interactive Elixir (1.4.0) - press Ctrl+C to exit (type h() ENTER for help)
iex(1)> Code.append_path "/home/deploy/.mix/archives/gatling/gatling/ebin/"
true
iex(2)> Gatling.Utilities.available_port
36296

The port number isn't the same as what in nginx config, but I assume that's because the app is currently running, so 39491 is no longer available.

IdahoEv · 2017-01-22T18:30:54Z

I tried a complete re-set today, deleting all relevant files on the server and starting over with a fresh install of gatling. I'm sorry this is so long -- but since we're 9 hours apart i thought it would reduce iteration time to include everything. Here are my config files, and I'll put the transcript of my attempt to deploy in the next post.

Interestingly: the site actually came up, despite the errors, which were the same as before. however I wasn't able to deploy an upgrade because the git repo on the server was left with uncommitted local changes to mix.lock.

Okay, here's the complete transcript of my attempt to deploy today, which had the same errors as yesterday. Despite the errors the site actually came up the first time, though when I try to push an update the changes do not get deployed.

ON SERVER: rename all relevant files and reboot

deploy@my-app:~$ mkdir disabled
deploy@my-app:~$ sudo mv tracker/ disabled/
deploy@my-app:~$ sudo mv .hex/ disabled/

deploy@my-app:~$ sudo mv /etc/init.d/tracker disabled/init.d-tracker
deploy@my-app:~$ sudo mv /etc/nginx/sites-available/tracker disabled/nginx-site-tracker

deploy@my-app:~$ sudo reboot

ON SERVER: reconnect after reboot, confirm environment vars are correct, install gatling and initialize the repo

I repeated a few iterations of bump version -> push code to try to trigger an upgrade. Each had the same errors as before. Inspecting the build tree to see what the releases look like shows that the .tar.gz file is never created in the numbered release directory. Also in browser I can confirm that none of the tweaks I made in 0.1.3 through 0.1.6 are live, it's still running 0.1.2 on the server.

I believe the issue described in #40 is the root cause of this, so closing this one for now.

It is needed for the seeds to run. Fixes #38.

adkron · 2017-01-25T18:25:18Z

I'm currently having this issue too. I just pulled down gatling yesterday. The init.d and the nginx files have the same number but the application endpoint says that :port is nil. It looks like the PORT environment isn't being passed into the application startup.

adkron · 2017-01-25T18:31:48Z

This fails on the ecto.setup task. I can pass in an arbitrary port number and get past it.

dennisreimann · 2017-01-25T19:00:36Z

@adkron Yes, it's fixed with 255d0d6 but there is no release with that fix yet.

IdahoEv mentioned this issue Jan 22, 2017

Release can't find .rel and so doesn't create .tar.gz file #39
