Cache mounts MUST be in the format --mount=type=cache,id=<cache-id>

I'm getting this error while trying to cache downloading a somewhat challenging to cache pip package:

RUN \
    --mount=type=cache,target=/var/cache/apt \
    pip3 download https://github.com/explosion/spacy-models/releases/download/en_core_web_sm-3.7.1/en_core_web_sm-3.7.1.tar.gz

RUN \
    --mount=type=cache,target=/var/cache/apt \
    pip3 download https://github.com/explosion/spacy-models/releases/download/en_core_web_sm-3.7.1/en_core_web_sm-3.7.1.tar.gz

This runs file locally and the package isn't redownloaded, but it fails on Railway with:

Cache mounts MUST be in the format --mount=type=cache,id=<cache-id>

Cache mounts MUST be in the format --mount=type=cache,id=<cache-id>

Why is id mandatory, and why is it missing the target field?

Solution:

--mount=type=cache,id=s/<service id>-/root/cache/pip,target=/root/.cache/pip

--mount=type=cache,id=s/<service id>-/root/cache/pip,target=/root/.cache/pip

the id is the service id, but I'll get you the correct format when I'm back at my computer

doesn't seem like I can use:

RUN \
    --mount=type=cache,id=var/cache/apt \
    pip3 download https://github.com/explosion/spacy-models/releases/download/en_core_web_sm-3.7.1/en_core_web_sm-3.7.1.tar.gz

RUN \
    --mount=type=cache,id=var/cache/apt \
    pip3 download https://github.com/explosion/spacy-models/releases/download/en_core_web_sm-3.7.1/en_core_web_sm-3.7.1.tar.gz

Because that wouldn't really cache it I guess...

Brody•10mo ago

i mean theres not even a service id there

SHxKMOP•10mo ago

You're correct, but specifying id without target doesn't help (no matter what the ID is)

Solution

--mount=type=cache,id=s/<service id>-/root/cache/pip,target=/root/.cache/pip

--mount=type=cache,id=s/<service id>-/root/cache/pip,target=/root/.cache/pip

Thanks Brody, trying to go a different way about this but this will surely come handy!

Brody•10mo ago

no problem

SHxKMOP•10mo ago

@Brody :

id=s/<service id>-

id=s/<service id>-

the s/ and the - are intetional, correct?

Brody•10mo ago

yes

SHxKMOP•10mo ago

Ahhh but unfortunately I'm using the same Dockerfile for two services...sigh

Brody•10mo ago

might have to forgo the cache then
