docker - Can I docker pull directly into local registry without re-tag and push?
I am trying to build a multi-GB docker image for machine learning using Python in Github Actions running with buildx.
To test a speedup of the builds I wanted to split the application Dockerfile into "application" image that's coming from (FROM) a "packages" image so that if Python requirements haven't changed I wouldn't have to build it every time (i.e. a sort of a cache layer).
My Github Actions workflow goes with something like this:
- Determine if there exists a "packages" image with the same
requirements.txtfile hash tag. - If not, build this "packages" image, tag it with a hash of the
requirements.txtfile and push the image to AWS ECR as well as to a local registry, skip to 4. - If yes, download the "packages" image and push it to a local registry.
- Use local registry "packages" image as the
FROMin a multi-stage build of the "application" image.
Step 3 is supposed to speed up the builds but since I have to go through a local registry in order for step 4 to work, I lose all leverage I gained.
Can I docker pull an image directly into a local registry?
Right now, going through docker tag && docker push into the local registry takes extra minutes.
Any help is appreciated.
docker - ベース イメージが異なる Docker buildx
amd64および Nvidial4tプラットフォーム用のイメージをビルドしたいと考えています。今、私は基本イメージ名amd64/debian:buster-slimをnvcr.io/nvidia/l4t-base:r32.6.1myに渡しDockerfileます。次に、シェル スクリプトを実行してdocker build、異なる基本イメージ名を--build-arg.
docker buildx非常に興味深いと思われるものについて読んだことがあります。ただし、ターゲット プラットフォーム用に異なるベース イメージを定義する方法がわかりません。
これは可能ですか？
