Occasional freeze with many docker workspaces on 1 big machine
Ok so I think I got myself into trouble with https://pad.ws
Here's my very naïve setup:
I run Coder on a single machine with docker compose, 125GiB and 32cpu as you can see in the screenshot
At the time i'm writing this, there is 160+ workspaces (75 currently running)...
Does the Jetbrains Gateway module only support AMD64 hosts?
When we try to use the Jetbrains Gateway module on an ARM64/AARCH64 host, the client hangs and we get this error inf the jetbrains stderr.log file on the worker:

It works OK on AMD64. Is this a known issue?...The provider coder/coder does not support data source "coder_git_auth".

jfrog oauth not working
Hey
I am trying to setup an external auth config for artifactory. I’ve been following the docs here. https://coder.com/docs/admin/integrations/jfrog-artifactory
I have set the following for my coder deployment
...
Solution:
Ahhh never mind I found the issue, in the jfrog integration config the callback url was referencing our prod instance not staging. Silly me.
I'm using traefik to handle ssl for coder - will this create any security issues?
Is there anything else that I should pay attention to? I've attached docker compose for the containers running on my server.
performance local hosted version
At our office we are trying to get a local server setup for a a couple of devs to use. We are however having a lot of performance issues when we are trying to run our development environment.
When using npm run dev our performance is not acceptable. We are suspecting it might be because of the cpu's single thread performance. Does coder have any recommended CPU's or other hardware requirements to run the workloads smoothly?
Thank you in advance....
Solution:
It's only specifically an issue when running npm run dev. After further investigation we saw our CPU is bad at single threaded workloads which the npm run dev is. When testing it on a system with a different cpu with higher single thread performance
if there a way to limit resource usage for each workspace?
for example, workspace can only use 10 cores and 16 GB max, etc.

newbie question :)
hello all! so i setup a self-hosted instance of coder. I am using the out of the box docker devcontainer workspace template.
I chose the custom url which points to my personal github repository.
I followed the guide where I needed to create a github oauth app. I got the callback url, client secret id and client id setup as env vars to the systemd service running coder. how do I provide my git credentials to the workspace?
however, when i launct he worksspace i get this error...
How to use External Auth to pull down Github NPM packages?
HI! I'm experimenting with Coder right now how it hooks up with Github. I've got it connected into Github for user-authentication, as well as configured for external auth. We can spin up a workspace that checks out code using the
github_token returned by the auth, and we've verified that the token then has access to other repositories that the user has access to. So far so good.
Where we're struggling now is using the same token to access Github's package repository (NPM). Here's what we've done so far:
1. Made sure the Github App has read:packages permissions....how do I get in touch with enterprise sales? email doesn't seem to work.

Bloomberg bindings
I have a bloomberg terminal that offers an api (https://data.bloomberglp.com/professional/sites/10/2017/03/BLPAPI-Core-Developer-Guide.pdf) with C++, JAVA, C# bindings - https://www.bloomberg.com/professional/support/api-library/
The typical pattern is you log into your terminal (using biometrics) and when your session is active you can use the API. This is a good way to pilot / test things before going to prod.
Any ideas on how I could do this using coder? Is there a way that I can use some proxy/portforwarding thing to the connect my vscode workspace back to my own laptop running the bloomberg terminal?...

envbuilder clone a private git repository?
- I've added my Coder SSH public key to github.
- I'm using a template based on the aws-devcontainer template.

Solution:
Just to follow up on this for anyone else searching here for a solution, you can set the following in your Terraform locals:

envbuilder_env = {
