Caveats

openssl

The alpine linux install doesn't build with this dependency. You can either compile native-tls with the vendored feature, or not use openssl.

If possible, use rustls instead.

vendoered native-tls

This crate must use the vendored feature in order to compile in the Alpine Linux image.

native-tls = { version = "0.2", features = ["vendored"] }

Don't use openssl

Check that none of your dependencies require openssl:

cargo tree --edges normal -i openssl

This will list the tree of dependencies that are bringing in openssl.

If you do need ssl/tls, try using rustls. e.g.

reqwest = { version = "0.12", default-features = false, features = [
  "json",
  "rustls-tls",
] }
