How to build docker container from source?

[Ethanol6]

I wouldn't mind attempting to contribute but my experience with docker is just in running other peoples containers, never building my own. My initial attempts to run docker build have not worked. I have not seen anything in the documentation about building Podfetch specifically.

I've tried this so far:

sudo docker build -t podfetch-test -f Dockerfile_cross_postgres .

Which results in:

=> ERROR [amd64 2/2] COPY ./target/x86_64-unknown-linux-musl/release/podfetch /app/podfetch                 0.0s

The problem with Docker builds for Rust is that you have to have everything in your Docker container. For that I used blackdex/rust-musl images that rely on the musl c compiler instead of libgcc that links dynamically things.
Additionally Rust generates a platform dependant code.

So if you want to run PodFetch on your own machine. You need to run the following commands which will prepare your executables

docker run --rm -v armv7prod:/root/.cargo -v "$(pwd)":/home/rust/src blackdex/rust-musl:x86_64-musl-stable cargo build --release --features postgresql
docker run --rm -v x86prod:/root/.cargo -v "$(pwd)":/home/rust/src blackdex/rust-musl:aarch64-musl-stable cargo build --release --features postgresql
docker run --rm -v arm64prod:/root/.cargo -v "$(pwd)":/home/rust/src blackdex/rust-musl:armv7-musleabihf-stable cargo build --release --features postgresql

Now you should have all 3 executables for all platforms. After that you just do :

docker buildx bake --set ".tags=samuel19982/podfetch:latest" --set '.dockerfile=Dockerfile_cross_postgres'

Then you should have the Docker image of PodFetch for all available platforms

Thanks a lot. One issue. There is no Cargo.toml file in my /home/rust/src. In fact there is no /home/rust/src directory at all. I tried using ~/git/PodFetch so it could find the Cargo.toml file in the git repo but I get the same error, it still says /home/rust/src is missing.

If I make the directory /home/rust/src and copy the Cargo.toml file from the git repo into it then it works but I get compilation errors when /home/rust/src/static/index.html can't be found. So there is some issue with my directory structure here.

Oh. You need to have PodFetch cloned on your machine (git clone https://github.com/SamTV12345/PodFetch.git) and then execute the docker run command there. But before that you need to create the index.html file in static. This can be done by doing pnpm run build in the ui directory and copying everything from the dist folder to the static folder.

Yes, PodFetch is cloned already. This seems to have worked except for docker run --rm -v armv7prod:/root/.cargo -v "$(pwd)":/home/rust/src blackdex/rust-musl:x86_64-musl-stable cargo build --release --features postgresql returns:

error: failed to remove file /home/rust/src/target/x86_64-unknown-linux-musl/release/podfetch

And when running the final command docker buildx bake --set ".tags=samuel19982/podfetch:latest" --set '.dockerfile=Dockerfile_cross_postgres' I get this:

[+] Building 0.0s (1/1) FINISHED                                 docker:default

Appreciate all the help!
