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
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
The output was:
quirks-6.42 signed on 2023-01-13T18:22:41Z
protobuf-3.21.6: ok
Build pict-rs server
Switch to _lemmy:
$ doas su - _lemmy
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
The output was:

You are in 'detached HEAD' state. 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
Then run to build:
$ cargo build --release
The output was:
Updating git repository `https://github.com/asonix/rust-s3`

Finished release [optimized] target(s) in 20m 35s
Now you can run pict-rs server with -p option to specify data directory:
$ cargo run --release -- -p data
The output was:
Finished release [optimized] target(s) in 0.24s

Additionally, you can specify address to listen:
$ cargo run --release -- -a 127.0.0.1:8080 -p data
Additionally, you can modify its configuration:
$ nvim pict-rs.toml
For example:
- api_key = 'API_KEY'
- image_format = 'jpeg'
- opentelemetry_url = 'http://localhost:4317/'
+ opentelemetry_url = 'http://127.0.0.1:4317/'
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 = "(...)"
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}/*"
]
}
]
}
Conclusion
Well done :) Go on to the next step.
