slurm-docker-cluster Dockerfile gosu Update

[dronixpro]

What problem are you trying to solve?

On my windows machine this task fails due to key server issues:

Line 57:

 RUN set -ex \
     && wget -O /usr/local/bin/gosu "https://github.com/tianon/gosu/releases/download/$GOSU_VERSION/gosu-amd64" \
     && wget -O /usr/local/bin/gosu.asc "https://github.com/tianon/gosu/releases/download/$GOSU_VERSION/gosu-amd64.asc" \
     && export GNUPGHOME="$(mktemp -d)" \
     && gpg --batch --keyserver hkps://keys.openpgp.org --recv-keys B42F6819007F00F88E364FD4036A9C25BF357DD4 \
     && gpg --batch --verify /usr/local/bin/gosu.asc /usr/local/bin/gosu \
     && rm -rf "${GNUPGHOME}" /usr/local/bin/gosu.asc \
     && chmod +x /usr/local/bin/gosu \
     && gosu nobody true

Describe the solution you’d like

I updated the dockerfile to this to get it to work:

RUN set -ex \
    && wget -O /usr/local/bin/gosu "https://github.com/tianon/gosu/releases/download/$GOSU_VERSION/gosu-amd64" \
    && echo "bbc4136d03ab138b1ad66fa4fc051bafc6cc7ffae632b069a53657279a450de3  /usr/local/bin/gosu" | sha256sum -c - \
    && chmod +x /usr/local/bin/gosu \
    && gosu nobody true

Describe any alternatives you’ve considered

This could be added as an optional resource for the users to implement. This would be just an update to the installation.md file.

Documentation, Adoption, Migration Strategy

Will be able to be used in the standard workflow.
