### Dockerfile.testing
## Intended to provide a reproducible testing environment for PixivFE
## Not for production use; please use the regular Dockerfile instead if you want to host PixivFE
## Adapted from: https://github.com/playwright-community/playwright-go/blob/6b672dbd24505206feca7c2b660da8d616c6393f/Dockerfile.example

### Instructions:
## To build and run with Playwright (default):
# docker buildx build -t pixivfe-testing -f ./Dockerfile.testing . --load
# docker run --rm -it --name pixivfe-testing pixivfe-testing

## To build and run without Playwright:
# docker buildx build -t pixivfe-testing-no-playwright -f ./Dockerfile.testing --target no-playwright . --load
# docker run --rm -it --name pixivfe-testing-no-playwright pixivfe-testing-no-playwright

### Notes:
## Likely can be made more DRY, but this works well enough

### Stage 1: Modules caching with correct Playwright CLI version
FROM golang:1.22.5-bookworm AS modules
COPY go.mod go.sum /modules/
WORKDIR /modules
RUN go mod download
RUN PWGO_VER=$(grep -oE "playwright-go v\S+" ./go.mod | sed 's/playwright-go //g') \
    && go install github.com/playwright-community/playwright-go/cmd/playwright@${PWGO_VER}

### Stage 2a: Final without Playwright
FROM ubuntu:noble AS no-playwright

WORKDIR /app

# Install correct Go version
ADD https://golang.org/dl/go1.22.5.linux-amd64.tar.gz /usr/local
RUN tar -C /usr/local -xzf /usr/local/go1.22.5.linux-amd64.tar.gz && rm /usr/local/go1.22.5.linux-amd64.tar.gz

# Update PATH definition for Go binary
ENV PATH="/usr/local/go/bin:${PATH}"

# Copy the project directory
COPY . /app

RUN go build -o /app/pixivfe

# Set the entrypoint to the binary name
ENTRYPOINT ["/app/pixivfe"]

### Stage 2b: Final with Playwright (default)
FROM ubuntu:noble

WORKDIR /app

# Copy resources from modules stage
COPY --from=modules /go/pkg /go/pkg
COPY --from=modules /go/bin/playwright /go/bin/playwright

# Install correct Go version
ADD https://golang.org/dl/go1.22.5.linux-amd64.tar.gz /usr/local
RUN tar -C /usr/local -xzf /usr/local/go1.22.5.linux-amd64.tar.gz && rm /usr/local/go1.22.5.linux-amd64.tar.gz

# Update PATH definition for Go binary and Playwright
ENV PATH="/usr/local/go/bin:/go/bin:${PATH}"

# Run playwright install --with-deps
RUN apt-get update && apt-get install -y ca-certificates tzdata \
    # Install dependencies and all browsers (or specify one)
    && playwright install --with-deps \
    && rm -rf /var/lib/apt/lists/*

# Copy the project directory last to avoid invalidating the cache for the Playwright installation
COPY . /app

RUN go build -o /app/pixivfe

# Set the entrypoint to the binary name
ENTRYPOINT ["/app/pixivfe"]
