Run azurite using pm2

[waygee]

Is it possible to run azurite using pm2 process manager for nodejs?

I would like to do something like:

cd /dir/where/azurite
pm2 start someprocess.js

Thanks for your help in advance.

Good point @waygee ! I do not see a reason why pm2 should not work with Azurite. There are two points, however, that need to be considered IMHO:

• executing Azurite on multiple cores (resulting in multiple processes) can lead to race conditions since it is not stateless. Azurite stores metadata in an in-memory database which is persisted every 5 seconds to disk.
• graceful shutdown is not supported yet as SIGINT is not intercepted yet. Happy to add support for that.

Thoughts?

Thanks for your response @arafato, in regards to the issues you raise:

I intend to run Azurite in a single thread (in forked mode in pm2), so I believe I can get by with the first limitation.

In addition, I am intending to use Azurite in a vagrant virtual machine for dev/testing purposes so I think it would be ok to not have graceful shutdown right away. Thank you for considering to add support for graceful shutdown, it would be very welcome.

I originally opened the issue to get the correct command line syntax for starting azurite using pm2. Can you help supply the actual command that I would need to run?

Assuming that Azurite has beed installed globally with $ npm install -g azurite, you can run it with pm2 as follows:
Under Linux you can simply start it with $ pm2 start azurite.
Under Windows there seems to be a bug with starting globally installed packages. See Unitech/pm2#2037 for details. This also affects Azurite.

You can, however, install it locally into some folder. Assuming that we are in c:\\local\folder, execute the following steps:
You install it locally with
npm install azurite
cd node_modules\azurite
pm2 start bin\azurite

@waygee Does this work for you? If not please re-open this issue.

I've also just added support for graceful shutdown. Will be published in the next few days as v0.7.10.

@waygee just published v0.7.10 which brings support for graceful shutdown for PM2.
