Get Caching to work

[chrisaxiom]

Not sure why, but I couldn't figure out how to get the cache dirs to work for zest build - it would be cool as it would save time.

Does this mean the CACHE_DIR_SRC to CACHE_DIR_DST mounting is actually not working?
I was working on making these arrays (CACHE_DIR_SRCS and CACHE_DIR_DSTS) to support multiple cache directories.

Well, for IQT I got it to work, sort of. I was able to move the integration tests into ./integrator, and treat that as a separate service. It compiles because I have

CACHE_DIR_SRC=$(pwd)/../
CACHE_DIR_DST=/go/src/github.com/iqt/raoc-api

This gets fed into compose via

_debug "Including cache directory $CACHE_DIR_SRC => $CACHE_DIR_DST"
docker run --rm -v $(pwd):$MOUNT_DIR/$SERVICE -w $MOUNT_DIR/$SERVICE -v $ZESTER_PATH:/usr/bin/zester:ro -v $CACHE_DIR_SRC:$CACHE_DIR_DST $BUILD_CONTAINER zester build --name $SERVICE

So in other words, its pulling in files that it needs up a directory. But this is not the same as "oh, you already built this stuff, here are the objects, so don't build again". I tried doing this:

CACHE_DIR_SRC=${GOPATH}/pkg
CACHE_DIR_DST=/go/pkg

but it didn't work :(

If you can figure out how to get this to work that would be awesome, as that is the last remaining pain point that I see with a full docker based dev environment.

@chrisaxiom Is all the Go code in /go inside the container? Maybe check that? Maybe it's in /root/go or sth like that

[chrisaxiom]

Dockerfile says ENV GOPATH /go

[chrisaxiom]

maybe we need to do something like -v $CACHE_DIR_SRC:$CACHE_DIR_DST where CACHE_DIR_SRC=./pkg and CACHE_DIR_DST=/go/pkg

[chrisaxiom]

Or something like this
