I'm building gogs from source and using
COPY gogs /home/git/go/src/github.com/gogits/gogs
to add the folder containing the built gogs bin and it's files to my container.
If I cd to /home/git/go/src/github.com/gogits/gogs I can see the file, I can chmod +x it , ls -l it to see permissions and ownership etc etc. However I can't seem to run it. Every way I try I get:
/home/git/go/src/github.com/gogits/gogs # cat /var/log/gogs/stderr.log
/bin/ash: /home/git/go/src/github.com/gogits/gogs/gogs: not found
/bin/ash: /home/git/go/src/github.com/gogits/gogs/gogs: not found
/bin/ash: /home/git/go/src/github.com/gogits/gogs/gogs: not found
Running ls -l . within the gogs directory:
/home/git/go/src/github.com/gogits/gogs # ls -l .

Other stuff I've tried:
/home/git/go/src/github.com/gogits/gogs # cp gogs /usr/bin
/home/git/go/src/github.com/gogits/gogs # /usr/bin/gogs
ash: /usr/bin/gogs: not found
/home/git/go/src/github.com/gogits/gogs # ls /usr/bin | grep gogs
gogs
/home/git/go/src/github.com/gogits/gogs # /usr/bin/gogs
ash: /usr/bin/gogs: not found
/home/git/go/src/github.com/gogits/gogs # ./usr/bin/gogs
ash: ./usr/bin/gogs: not found
/home/git/go/src/github.com/gogits/gogs # ls /usr/bin/gogs
/usr/bin/gogs
Exec'ng into the docker container with the command sh I start to get weird errors after sometime, it may be tend to happen after I've added to PATH the gogs bin, can't remember for sure, but this has happened before
/home/git/go/src/github.com/gogits/gogs # gogs
sh: gogs: not found
/home/git/go/src/github.com/gogits/gogs # ./gogs
sh: ./gogs: not found
/home/git/go/src/github.com/gogits/gogs # export PATH=PATH:/home/git/go/src/github.com/gogits/gogs
/home/git/go/src/github.com/gogits/gogs # gogs
sh: gogs: not found
/home/git/go/src/github.com/gogits/gogs # cp gogs /usr/bin
sh: cp: not found
/home/git/go/src/github.com/gogits/gogs # cp gogs /usr/bin
sh: cp: not found
/home/git/go/src/github.com/gogits/gogs # cp
sh: cp: not found
/home/git/go/src/github.com/gogits/gogs # ls
sh: ls: not found
Also when I did try to build gogs from source within the container I got a Segmentation Fault (core dump) sth like that. I tested it with valgrind and got sth like Bad permissions for mapped region at address 0x1340F80

The main problem is that you're using an image which doesn't have the Go libraries needed. I suspect that you're also not compiling your Go application for your target OS.
Cross compile
If you're compiling your app in Mac or Windows, you have to cross compile it. To target 64 bit linux (Debian/Ubuntu), it's like this.
GOOS=linux GOARCH=amd64 go build -o myapp_linux-amd64 .
The flags for other OS's are here https://golang.org/doc/install/source#environment.
It's a good idea to name your output binary with the name of the target platform (_linux-amd64).
Use the official golang:1.7 image
That's the simplest way to do it. The image will already include all the libraries needed.
Later on, you can look into optimising your image size. That's when static linking and Alpine becomes useful but they have their own sets of gotchas (no libc so DNS might not resolve correctly depending on your app). They can be worked around but it might not be worth your time now.
