What if we go straight to supported version 1.22 on bullseye so long as there's no breaking changes? Feels like being on latest supported is what we want if we're changing this.

Yes, I fully agree. I was playing safe with 1.19.

Ok since it's testing ok, let's go with the 1.22, bullseye and bookworm changes. Are you ok with updating your PR for this?

Used the same bookworm version for both build and run containers.

WORKDIR /dir
COPY app.go .
RUN go get -d -v
COPY app.go go.mod go.sum ./
RUN CGO_ENABLED=0 GOOS=linux go build -a -installsuffix cgo -o app .

Similar idea. how about we do bookworm instead so we're on latest supported/patched?

Note I tested your suggestion and my suggested changes and both work at runtime and are compatible.
