I create //deploy when I first deployed a few applications that I packaged with Nix. This was before I setup socrates as my "cloud". Now I deploy all of my services using NixOS. The name "deploy" is a bit stale. I'm renaming it //nix_gcr because it documents how I can deploy Nix-packaged projects on Google Cloud Run.

# Nix + Google Cloud Run (i.e. GCR)
|
|
|
|
I'm documenting how I currently deploy projects that I package with Nix on
|
|
Google Cloud Run.
|
|
|
|
I'd like to automate this workflow as much as possible, and I intend to do just
|
|
that. For now, I'm running things manually until I can design an generalization
|
|
that appeals to me.
|
|
|
|
## Dependencies
|
|
- `nix-build`
|
|
- `docker`
|
|
- `gcloud`
|
|
|
|
## Step-by-step
|
|
|
|
1. Use `nix-build` to create our Docker image for Cloud Run.
|
|
|
|
```shell
|
|
> nix-build ./cloud_run.nix
|
|
```
|
|
|
|
This outputs a Docker image at `./result`.
|
|
|
|
1. Load the built image (i.e. `./result`) into `docker` so that we can tag it
|
|
and push it to the Google Container Registry (i.e. GCR).
|
|
|
|
```shell
|
|
> sudo docker load <./result
|
|
```
|
|
|
|
1. (Optionally) Run the image locally to verify its integrity.
|
|
|
|
```shell
|
|
> sudo docker run -d -p 8080:4242 <name>:<tag>
|
|
```
|
|
|
|
1. Tag and push the image to GCR.
|
|
|
|
```shell
|
|
> sudo docker tag <name>:<label> gcr.io/<google-cloud-project-id>/<name>:<latest>
|
|
```
|
|
|
|
1. Visit Google Cloud Run; create a new service with "Create Service"; select
|
|
the uploaded Docker image from the "Container Image URL" field; click
|
|
"Create" to deploy.
|
|
|
|
## Notes
|
|
|
|
You may need to authorize `gcloud` by running the following:
|
|
|
|
```shell
|
|
> sudo gcloud auth login --no-launch-browser
|
|
```
|
|
|
|
You must use `sudo` here since the `docker` invocations are prefixed with `sudo`
|
|
as well.
|
|
|
|
## Todos
|
|
|
|
- If possible, prefer using a command line tool like `gcloud` to create the
|
|
Cloud Run service.
