Hi ! Sorry noob question again : I have a docker image built locally that I want to use with Minikube. When I tried to rebuild it after setting up env variable with

eval $(minikube docker-env)

and try to pants package the dockerfile again, I have this :

ProcessExecutionFailure: Process 'Building docker image recital/n20-dev:latest.' failed with exit code 1.
stdout:
stderr:
2021/12/13 16:15:16 http2: server: error reading preface from client 192.168.49.2:2376: bogus greeting "Client sent an HTTP requ"
read tcp 192.168.49.1:38404->192.168.49.2:2376: read: connection reset by peer

I assume that I have to change docker context in pants.toml (DOCKER_HOST value in [docker]) but I still get the same error.

Docker built . -t {imagetag:version}

doesn’t work either. Thanks for help 🙂

Hi 🙂 Do I understand you correctly that if you run

docker build …

directly from your terminal, that it doesn’t work? In that case, getting that to work first, is probably a good first step. What is the error output in that case?

Thanks for your answer @curved-television-6568. I have this :

OK, so you don’t seem to have a

Dockerfile

in you current directory.. do you use a Dockerfile, or

instructions

on your

docker_image

target?

Yes it doesn't find any dockerfile. The one I'm trying to get is located in services/n20/Dockerfile : Dockerfile:

RUN wget <https://github.com/tesseract-ocr/tessdata/raw/4.00/lat.traineddata> -P /usr/share/tesseract-ocr/4.00/tessdata

and in the build file (located at services/n20) :

docker_image(
    name="n20",
    dependencies=["src/python/n20:wheel", ":resources"],
    image_tags=["{build_args.BITBUCKET_BUILD_NUMBER}"],
    extra_build_args=["--secret id=pipconfig,src=pip.conf"],
    repository="recital/n20-dev",
)

files(
    name="resources",
    sources=["resources/*"],
)

so you’d want to run this from your project root:

docker build -t recital/n20-dev -f services/n20/Dockerfile .

and make sure to have your

.dockerignore

properly skip files you don’t need, so you don’t get Gb of build context… 😉

Thanks !! I'm going to try this

When that works (or at least, docker attempts to build, but maybe fail due to missing dependencies, such as wheel files) we can try to get it to work using

./pants package

🙂

ha yes ! Indeed I have a .whl that missing after starting building correctly :

OK, so back to minikube, look at what

minikube docker-env

tells you, and put those env vars into your

pants.toml

file under

[docker].env_vars

(with just the names, as it will pick up the values from your env)

ok thanks you very much again 🙂

Your’re welcome. Happy it works! 😄
