Here’s an example dockerfile I wrote (for a different project) that’s a little more transparent
FROM alpine:3.18.2
WORKDIR /root
RUN apk update && apk upgrade && apk add --no-cache git nodejs-current yarn
RUN git clone https://github.com/hydra-synth/hydra.git
WORKDIR /root/hydra
RUN yarn install
EXPOSE 8000
CMD ["yarn", "build"]
CMD ["yarn", "serve"]
You read the Dockerfile https://hub.docker.com/layers/masquernya/lemmy/0.18.2-linux-arm64/images/sha256-f1501bab2574cf371673d0926fdecd5b61e00d77e637ebc4f43a31ecbc029270?context=explore
To me the first line is pretty opaque
ADD file:1368964550b1f674dd0365f72bb1d55cfebf5e3c651d49b5e168f9be97a6df76 in /
Maybe that hash lines up with a version of Lemmy, otherwise it’s just a hash of a mystery block of files that could contain anything.
The only way I could get Lemmy running was to use yunohost
You’re unlikely to find an instance for general purpose video hosting as it’s too resource intensive to host for free. With no clear way to offset the costs the current M.O. is to upload videos to a 3rd party host that monetizes their services (usually through ads) and link to that 3rd party from your post.
