Autopilot fails on Alpine

[rjain-pivotal]

cloudfoundry/cli#1314

After looking into this issue, it appears that the plugin is actually not complied statically!

$ ldd autopilot-linux
linux-vdso.so.1 => (0x00007ffdb6394000)
libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f8b0a778000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f8b0a398000)
/lib64/ld-linux-x86-64.so.2 (0x00007f8b0a997000)
So it fails during the cf install-plugin step in your docker file because alpine Linux does not have those libraries. The CF CLI tries to run the plugin it's installing during the install-plugin phase to get metadata about said plugin and a segfault occurs, thus causing the error you see in front of you.

There are two solutions:

Compile the autopilot plugin yourself with the following build command:
$ CGO_ENABLED=0 GOARCH=amd64 GOOS=linux go build -a -tags netgo -installsuffix netgo -ldflags "-w -s -extldflags "-static"" -o autopilot-linux
