pict-rs 0.3.2 on OpenBSD 7.2: Install

#watercooler

Summary

This post is a part of Lemmy 0.16.7 on OpenBSD 7.2 about Lemmy.

Premise

The server is OpenBSD and Rust (rustlang) is installed. Also, there is _lemmy user whose home directory is /var/lemmy.

Environment

  • OS: OpenBSD 7.2
  • Object Storage: MinIO - AWS S3-compatible (Optional)
  • Apps
    • pict-rs: 0.3.2
    • based on Rust 1.63 + Actix Web 4 + Actix 0.13

Tutorial

pict-rs server

Lemmy uses pict-rs to store image. It is a simple image hosting service which is open source and written in Rust, too.

Prepare for the dependencies

You have to install protobuf, "Protocol Buffers - Google's data interchange format"

Therefore switch back to your own user if you are acting as _lemmy to install it:

$ exit  $ doas pkg_add protobuf
Enter fullscreen mode Exit fullscreen mode

The output was:

quirks-6.42 signed on 2023-01-13T18:22:41Z protobuf-3.21.6: ok
Enter fullscreen mode Exit fullscreen mode

Build pict-rs server

Switch to _lemmy:

$ doas su - _lemmy
Enter fullscreen mode Exit fullscreen mode

Get the source of the stable version (v0.4 didn't work in my case):

$ git clone https://git.asonix.dog/asonix/pict-rs.git --branch v0.3.2 --single-branch
Enter fullscreen mode Exit fullscreen mode

The output was:

Cloning into 'pict-rs'... remote: Enumerating objects: 2707, done. remote: Counting objects: 100% (2707/2707), done. remote: Compressing objects: 100% (1932/1932), done. remote: Total 2707 (delta 1806), reused 1077 (delta 687), pack-reused 0 Receiving objects: 100% (2707/2707), 2.21 MiB | 114.00 KiB/s, done.

You can look around, make experimental changes and commit them, and you can discard any commits you make in this state without impacting any branches by switching back to a branch. (...)

Go inside:

$ cd pict-rs
Enter fullscreen mode Exit fullscreen mode

Then run to build:

$ cargo build --release
Enter fullscreen mode Exit fullscreen mode

The output was:

 Updating git repository `https://github.com/asonix/rust-s3` (...) Compiling rustls v0.20.6 (...) Compiling actix-web v4.1.0 (...) Compiling pict-rs v0.3.2 (/var/lemmy/pict-rs) Finished release [optimized] target(s) in 20m 35s
Enter fullscreen mode Exit fullscreen mode

Now you can run pict-rs server with -p option to specify data directory:

$ cargo run --release -- -p data
Enter fullscreen mode Exit fullscreen mode

The output was:

 Finished release [optimized] target(s) in 0.24s Running `target/release/pict-rs -p data` 2023-01-14T12:51:58.377271Z INFO restructure{store=FileStore { path_gen: "generator", root_dir: "data" }}: pict_rs::store::file_store::restructure: new 2023-01-14T12:51:58.377478Z INFO restructure{store=FileStore { path_gen: "generator", root_dir: "data" }}: pict_rs::store::file_store::restructure: close time.busy=11.3µs time.idle=197µs 2023-01-14T12:51:58.377627Z INFO actix_server::builder: Starting 1 workers 2023-01-14T12:51:58.377736Z INFO actix_server::server: Actix runtime found; starting in Actix runtime
Enter fullscreen mode Exit fullscreen mode

Additionally, you can specify address to listen:

$ cargo run --release -- -a 127.0.0.1:8080 -p data
Enter fullscreen mode Exit fullscreen mode

Additionally, you can modify its configuration:

$ nvim pict-rs.toml
Enter fullscreen mode Exit fullscreen mode

For example:

- api_key = 'API_KEY'  - image_format = 'jpeg'  - opentelemetry_url = 'http://localhost:4317/' + opentelemetry_url = 'http://127.0.0.1:4317/'
Enter fullscreen mode Exit fullscreen mode
Integrate pict-rs with MinIO (Optional)

pict-rs stores image files in their local directory by default.

Well, there is a way to introduce MinIO bucket usage by editting pict-rc.toml as below:

- type = "file_store" + type = "s3_store" + + region = "https://(minio-fqdn)" + bucket_name = "(...)" + access_key = "(...)" + secret_key = "(...)"
Enter fullscreen mode Exit fullscreen mode

and, of course, creating MinIO bucket and service account, with bucket policy like:

{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "admin:*" ] }, { "Effect": "Allow", "Action": [ "s3:*" ], "Resource": [ "arn:aws:s3:::{bucket-name}", "arn:aws:s3:::{bucket-name}/*" ] } ] }
Enter fullscreen mode Exit fullscreen mode

Conclusion

Well done :) Go on to the next step.
