带有Cloud Foundry CLI的Golang Docker

I use the following dockerfile and when I build and run it I got error that **unknown command cf**, I set the env and I expected that when I run cf -v it will print the version,what it could be ?

FROM golang:1.10.5

ENV CF_CLI_VERSION "6.40.0"

RUN ln -s /lib/ /lib64
RUN apt-get update && apt-get install curl -y
ENV CF_HOME=/usr/local/bin

RUN curl -L "https://cli.run.pivotal.io/stable?release=linux64-binary&version=${CF_CLI_VERSION}" | tar -zx -C /usr/local/

You probably want to change the last line to

RUN curl -L "https://cli.run.pivotal.io/stable?release=linux64-binary&version=${CF_CLI_VERSION}" | tar -zx -C /usr/local/bin

/usr/local is not in the PATH by default
