How to find Service ID - Docker Cache Mounts

Hi, how can i find my service id? I have cache mounts in my dockerfile, and railway wants me to provide an id, which I've been told is supposed to be my service id.

Project ID: N/A

You can find your service ID in the URL when you go to your service railway.app/project/PROJECT_ID/service/SERVICE_ID

sorry, i'm now getting Cache mount ID is not prefixed with cache key offending code RUN --mount=type=cache,id=<service_id>,target=/go/pkg/mod/ \

RUN --mount=type=cache,id=s/<service id>-/root/cache/go-build,target=/root/.cache/go-build go mod download

RUN --mount=type=cache,id=s/<service id>-/root/cache/go-build,target=/root/.cache/go-build go mod download

same for go build

It's now throwing: Invalid cache mounts However, it still works locally. full example RUN --mount=type=cache,id=s/<service_id>/root/cache/go-build,target=/root/.cache/go-build \ --mount=type=bind,source=go.sum,target=go.sum \ --mount=type=bind,source=go.mod,target=go.mod \ go mod download -x do i need to change the targets?

Brody•7mo ago

please try with the exact line I gave before you start modifying it

Mopsican•7mo ago

ok, it's just i need to use RUN --mount=type=cache,id=s/<service_id>/root/cache/go-build,target=/root/.cache/go-build \ apk --update add \ ca-certificates \ tzdata \ && \ update-ca-certificates and RUN --mount=type=cache,id=s/<service_id>/root/cache/go-build,target=/root/.cache/go-build \ --mount=type=bind,target=. \ CGO_ENABLED=0 GOARCH=$TARGETARCH go build -o /bin/server ./ as well #11 0.400 go: no modules specified (see 'go help mod download') it doesn't seem to like bind mounts

Brody•7mo ago

are you making sure to copy in your go.mod and go.sum files before running go mod download? yes so don't use them lol how about you send your current dockerfile? I've only ever used my own dockerfiles that don't use mount catches and build time is always somewhere around 10 or 15 seconds for the entire build

please enclose it in triple backticks looks kinda overly complex tbh

Mopsican•7mo ago

maybe, i just need to get the exe, mod and sum + the last 2 lines

Brody•7mo ago

exe huh?

Mopsican•7mo ago

i mean get the build

keep it simple

Mopsican•7mo ago

thanks managed to do it, just needed to copy local packages and files as well

WORKDIR /blog

COPY go.mod go.sum ./
COPY ./shared/ ./shared/
COPY ./tem/ ./tem/
RUN go mod download

COPY ./blogPosts/ ./blogPosts/
COPY *.go ./
RUN go get ./shared/
RUN go get ./tem/
RUN go install
RUN ls *


RUN GO111MODULE=on CGO_ENABLED=0 GOOS=linux go build -a -installsuffix cgo -o main


FROM alpine:latest as final

WORKDIR /blog

COPY --from=build /blog/main ./
COPY --from=build /blog/blogPosts ./blogPosts/

ENTRYPOINT ["/blog/main"]
