Switch user, group and execute a program
To use this package, put the following dependency into your project's dependencies section:
goinsu - a simple
su which doesn't mess with TTY and other stuff. It is as simple as "Hey, run this program as this user".
$ docker run -it --rm ubuntu:trusty su -c "ps aux" USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 1 7.0 0.0 46644 2628 pts/0 Ss+ 19:07 0:00 su -c ps aux root 7 0.0 0.0 15584 2100 ? Rs 19:07 0:00 ps aux $ docker run -it --rm ubuntu:trusty sudo ps aux USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 1 7.0 0.0 46028 3044 pts/0 Ss+ 19:07 0:00 sudo ps aux root 6 0.0 0.0 15584 2140 pts/0 R+ 19:07 0:00 ps aux $ docker run -it --rm -v`pwd`/goinsu:/usr/bin/goinsu ubuntu:trusty goinsu root ps aux USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 1 0.0 0.0 7152 852 pts/0 Rs+ 19:08 0:00 ps aux
Why reinvent gosu?
goinsu does the same thing but in 10KB (well, 50KB if compiled as a static executable) instead of 1.8MB.
Why reinvent su-exec?
goinsu is written in the D programming language, which is a high-level programming language with metaprogramming, CTFE, and other cool things you can't find in C.
Yep. goinsu written in a subset of the D programming language, called betterC. Just google for it, ya' know.
You can use
su-exec, but they aren't as cool as goinsu.
