Hello,
I am interested in a Go sandbox to execute arbitrary, untrusted Go code delivered via curl
.
I believe the most well-known sandbox like this is https://play.golang.org/
I found the github repo where this code lives (https://github.com/golang/playground) and I am trying to run the example they provide in the repo.
The README from the Github seems to suggest I can execute arbitrary code via a Docker image + curl
.
Here is the example from the README below.
docker build -t golang/playground .
docker run -d --name=play --rm -p 8080:8080 golang/playground
# run some Go code
cat /path/to/hello_world.go | go run client.go | curl -s --upload-file - localhost:8080/compile
While this seems straightforward, it isn’t working.
Issue seems to be a “SANDBOX_BACKEND_URL” environment variable.
ERROR MESSAGE:
#Golang Error
cmdFunc error: POST "http://sandbox_dev.sandnet/run": Post "http://sandbox_dev.sandnet/run": dial tcp: lookup sandbox_dev.sandnet on 127.0.0.11:53: no such host

2020/10/17 20:39:26 http: panic serving 172.17.0.1:60486:
no SANDBOX_BACKEND_URL environment and no default defined for project ""
Can anyone can help me understand the error and help me execute the code from the example?
