The task

Full task test is in pdf Test-task-for-DevOps.pdf

Build and run local server

cargo build
cargo run

Result executable sora-test-rust-web accepts PORT from environment variable.

Than server is accessable on http://127.0.0.1:PORT/ , default is 8000.

Rust and Cargo could be installed with brew install rust or use Dockerimage rust:latest docker run -it rust:latest, see Dockerfile.

Dockerfile, dockerimage

Build a docker image with executable server inside

docker build -tsora-devops-web .

Run it locally

docker run -p8000:8000 -ePORT=8000 sora-devops-web

Now server is accessable on http://127.0.0.1:8000/

I did not use docker image to push it and run on web - that is redundant. And it better works without additional layers.
