🐋 Need some help with Docker

[alexjustesen]

In a nutshell, I'm looking to make the Docker image used for this project lighter, faster and more efficient but I'm focused on adding features at the moment.

Could really use some help from the community to improve the image. Bonus points of someone can get LinuxServer involved to craft an awesome image.

There are also changes coming to the base image outline in #750

Hi Alex,

Would be happy to help but I'm lacking the knowledge about laravel, still learning it. I will try to build the image and see how I can slim it down a little bit, if that helps.

On hold for the moment, I'm using Serverside Up's image as the base which is currently going through some changes: #750

Alright, do you need help with it? I can test drive also on docker and I have an rpi somewhere I can spin up.

[alexjustesen]

At some point def, I just pinged the authors to see where they stand. Ideally I don't want to start using a new base until it hits at least beta.

Linuxserver team member here, I'd be happy to take a look at this, it's a fairly standard setup.

I've had a quick play around and I've knocked about 120Mb off the image size, but I am getting a production.ERROR: Trying to access array offset on value of type null error when actually running tests, which I've not been able to narrow down a cause of yet.

I was trying to be too clever, got a working POC now, about half the size of the current image.

docker.io/thespad/playground:speedtest-tracker if you want to give it a try, all the envs, etc. should be the same, though it only needs a /config mount. I've not tested with mysql/mariadb but it should work - postgres and sqlite both do.

Dude this is 🔥🔥🔥 thank you! I'm on a mini vacation until Monday but will get right on testing that image.

[alexjustesen]

@thespad couple of questions before testing later today or tomorrow...

1. How does the container utilize Laravel's queue and scheduler? Are you using cron or some task scheduler and process manager?
2. In the past I've had some issues with permissions within the container that effected how the cache works and writing of files, any changes there?

[thespad]

I pretty much just copied what you were already doing; the queue is a service, the scheduler is a cron job running every minute. I'm open to changing things around if you think there's a better way to approach it.

Permissions-wise I'm currently chowning:
/app/www/bootstrap/cache
/app/www/storage
/app/www/database
/config

To the running user.

Any chance you mind sharing the Dockerfile? In all honesty the Docker side of this project is my weakness so looking to boost my education there.

[thespad]

Sure, https://bin.spad.uk/?51ac931610eba73b#5RxDXYThJP3RWiUqy9869faehRKFTRf9Q4pVU8oFpRyk

Obviously doesn't include the s6 init/service components, crontabs, etc.

If you want to see the full image build I've pushed it to a dev branch here https://github.com/linuxserver/docker-speedtest-tracker/tree/initial
