docker-multi-stage-build

问题 I have a docker file that I can build locally without issues, on Azure Devops the variable is not set properly. E.g. locally I can run a multi-stage docker build where artifacts are fetched from an Azure artifact repository with authorization. The authorization token can be set locally without issues. On the build pipeline I haven't been able to inject it properly. The docker file: FROM gradle:5.4.1-jdk8 AS build ARG AZURE_ARTIFACTS_ENV_ACCESS_TOKEN ENV AZURE_ARTIFACTS_ENV_ACCESS_TOKEN $AZURE

问题 A new docker feature is to do something like this in the dockerfile FROM php7-fpm as build ... FROM build AS test ... FROM test AS staging ... As far as i know, the last FROM statement marks the final output image. How is it possible to have two final images from one intermdiate image? Like ... FROM build AS test ... FROM test AS staging ... FROM test AS prod Test, staging and prod should not be discarded. I want to check in them into the repository. 回答1: You can stop the build at a certain

问题 I am successfully using Docker's Multi-Stage feature to build some code and then copy the resulting artifacts into a final image. Is it possible to split this one big-ish Dockerfile into multiple files? I would like to improve the readability of the individual stages. Which will become more important when more stages are added. EDIT: I am aware that I could write a Makefile (or similar) where I first build an image named "myproject-stage1" and then use FROM myproject-stage1 AS build . However

问题 I am looking for a way to create multistage builds with python and Dockerfile: For example, using the following images: 1st image : install all compile time requirements, and install all needed python modules 2nd image : copy all compiled / built packages from first image to the second, without the compilers themselves (gcc, postgers-dev, python-dev etc..) The final objcetive is to have a smaller image, running python and the python packages that I need. In short: how can I 'wrap' all the

问题 I'm writing a multi-stage Dockerfile for the darshan utils: ARG DARSHAN_VER=3.1.6 FROM fedora:29 as build RUN dnf install -y \ gcc \ make \ bzip2 bzip2-devel zlib zlib-devel RUN curl -O "ftp://ftp.mcs.anl.gov/pub/darshan/releases/darshan-${DARSHAN_VER}.tar.gz" \ && tar ... FROM fedora:29 COPY --from=build "/usr/local/darshan-${DARSHAN_VER}" "/usr/local/darshan-${DARSHAN_VER}" ... I build it with docker build -t darshan-util:3.6.1 . and the error I get is: Step 5/10 : RUN curl -O "ftp://ftp

问题 Using multi-stage builds, I want to downsize an image at the end of Dockerfile, something like this: FROM ubuntu AS ubuntu_build RUN # do a lot of build things FROM alpine COPY --from=ubuntu_build /app /app ENTRYPOINT whatever the alpine image is small, and in theory only the /app stuff will get copied from the ubuntu image, is this the best trick in the book, or is there some other way to minimize the size of the final image? 回答1: Distroless Google provides instructions and tools to help

问题 I use Docker multi-stage build, specifically: Use an external image as a “stage” When using multi-stage builds, you are not limited to copying from stages you created earlier in your Dockerfile. You can use the COPY --from instruction to copy from a separate image, either using the local image name, a tag available locally or on a Docker registry, or a tag ID. The Docker client pulls the image if necessary and copies the artifact from there. The syntax is: In my case I have three Docker files
