I'm trying to build a Docker image for my Gitlab CI pipeline containing docker client + gcloud along with the following gcloud components:
- kubectl
- docker-credential-gcr
This is my dockerfile:
FROM docker:git
RUN mkdir /opt \
&& cd /opt \
&& wget -q https://dl.google.com/dl/cloudsdk/channels/rapid/downloads/google-cloud-sdk-152.0.0-linux-x86_64.tar.gz \
&& tar -xzf google-cloud-sdk-152.0.0-linux-x86_64.tar.gz \
&& rm google-cloud-sdk-152.0.0-linux-x86_64.tar.gz \
&& ln -s /opt/google-cloud-sdk/bin/gcloud /usr/bin/gcloud \
&& apk -q update \
&& apk -q add python \
&& apk add --update libintl \
&& apk add --virtual build_deps gettext \
&& cp /usr/bin/envsubst /usr/local/bin/envsubst \
&& apk del build_deps \
&& rm -rf /var/cache/apk/* \
&& echo "y" | gcloud components install kubectl docker-credential-gcr \
&& ln -s /opt/google-cloud-sdk/bin/kubectl /usr/bin/kubectl \
&& ln -s /opt/google-cloud-sdk/bin/docker-credential-gcr /usr/bin/docker-credential-gcr
Inside my CI flow, I need to run docker-credential-gcr (because of this issue).
The docker-credential-gcr executable is correctly installed inside /opt/google-cloud-sdk/bin like shown by running docker run -i -t gitlabci-test ls /opt/google-cloud-sdk/bin
It is also correctly simlinked inside /usr/bin as shown by docker run -i -t gitlabci-test ls -la /usr/bin
And yet, trying to call it with any of the methods below fails miserably
docker run -i -t gitlabci-test docker-credential-gcr
docker run -i -t gitlabci-test /usr/bin/docker-credential-gcr
docker run -i -t gitlabci-test /opt/google-cloud-sdk/bin/docker-credential-gcr
Error message:
/usr/local/bin/docker-entrypoint.sh: exec: line 20: docker-credential-gcr: not found
On the other hand, running the kubectl component works fine
docker run -i -t gitlabci-test kubectl version
Any idea how I can fix this issue to be able to run docker-credential-gcr with the container ?
