Docker build is failing

Question

I am trying to upload ca-certificate stored in my windows location to docker container but while running the build image it is failing.

I am not getting how to copy the certificate from windows location to linux recommended location.

Without this when I am trying to run using , it gives warning 0curl: (6) Could not resolve host:

and then could not run next command because of error spark-3.1.1-bin-without-hadoop.tgz: Cannot open: No such file or directory

RUN curl    -O --insecure  ./spark-3.1.1-bin-without-hadoop.tgz  -I https://archive.apache.org/dist/spark/spark-3.1.1/spark-3.1.1-bin-without-hadoop.tgz

RUN tar -xzf spark-3.1.1-bin-without-hadoop.tgz

If your pem file is outside of Docker and you are trying to copy it into Docker, You need to put the pem file besides your Dockerfile and use ADD or COPY instruction:

COPY bundle.pem /etc/pki/ca-trust/source/anchors/

and always its better to not to use relative path ~ in Dockerfiles.
