Service startup errors

[realies]

Upon booting the container up via docker-composer there is errors until something fully initializes:

$ docker-compose up

Hi,

Thank you for reporting this.

I know npm has had some issues this past week but I don't know if this could be related to that. Definitely not related to the npm issues this week. It looks like it has to do with sqs-insight loading much quicker than elasticmq. This was probably introduced by the use of dynamic endpoints.

I'll investigate 🕵️ 👀

Supervisord doesn't support process dependencies with the autostart feature;

See supervisor bug #122.

Workaround:
https://github.com/bendikro/supervisord-dependent-startup

Example:
https://github.com/bendikro/supervisord-dependent-startup/blob/master/example.md

I'll work on implementing this shortly.

@roribio This is perhaps a stupid question, but I haven't worked with python much. How do I implement that workaround? I've spent some time with the supervisord-dependent-startup package and I'm trying to build a new image of alpine-sqs with that package included. I've tried copying that full directory under /etc/supervisor and adding the following to supervisord.conf:

[eventlistener:dependentstartup]
command=python /etc/supervisor/supervisord_dependent_startup/supervisord_dependent_startup.py -c /etc/supervisor/supervisord.conf
autostart=true
events=PROCESS_STATE

However that doesn't seem to work. When I run this as a local_sqs container via docker-compose I get:

local_sqs_1  | 2019-02-21 06:22:46,611 INFO spawned: 'dependentstartup' with pid 13
local_sqs_1  | 2019-02-21 06:22:46,658 INFO exited: dependentstartup (exit status 1; not expected)

I'll be happy to submit a PR to fix this issue once I can figure out how to include this package. Do you have any advice?

[roribio]

Hey @JackWCollins,

Thanks for picking this up! I don't think it's a stupid question at all, I'm not a Python expert either.

I did some research and found a project that's using this same plugin, here. It's structured similarly as this project. Upon inspection, I conclude/assume the following:

• You can install the plugin using pip. See example here.

For non-editable installs, the project is built locally in a temp dir and then installed normally. Note that if a satisfactory version of the package is already installed, the VCS source will not overwrite it without an –upgrade flag. VCS requirements pin the package version (specified in the setup.py file) of the target commit, not necessarily the commit itself.

-- Reference: PIP User Manual - VCS Support.

• Apparently, pip is included with the alpine-base distribution and no further installation is required. I would double-check this is the case though.
• It seems pip installs binaries to /usr/local/bin on Alpine Linux. See example here.
• Once the plugin is installed and you configure the event listener, you can configure the startup order for services. There's an example for that, here.

I hope this helps! If you can get it to work, I'm glad to merge your changes and update the image on Docker Hub.

Thanks again,
Ronald
