Story: Writing Scripts with Go

This is a story about how I tried to use Go for scripting. In this story, I’ll discuss the need for a Go script, how we would expect it to behave and the possible implementations; During the discussion I’ll deep dive to scripts, shells, and shebangs. Finally, we’ll discuss solutions that will make Go scripts work.

Why Go is good for scripting?

While python and bash are popular scripting languages, C, C++ and Java are not used for scripts at all, and some languages are somewhere in between.

This is how I quickly got an Apache Zepplin notebook running against the AWS Glue Dev endpoint. None of the guides out there seemed concise, and I found some custom Docker containers doing what you can do easily. This gives you the power - it sets up port forwarding & runs the official Docker image.

1. Create your Glue Dev endpoint (this involves creating a keypair, I just used ssh-keygen)
2. Once READY, select it and copy the "SSH tunnel to remote interpreter"

• eg: ssh -i <private-key.pem> -vnNT -L :9007:169.254.76.1:9007 [email protected]

3. Connect to the endpoint in a terminal session, modifying the above to match: ssh -i ~/.ssh/glue-dev -vnNT -L :9007:*127.0.0.1*:9007 glue@<ec2-endpoint>.<region>.compute.amazonaws.com
4. Run the Apache Zepplin Docker container `docker run -p 8080:8080 --rm -v $PWD/logs:/logs -v $PWD/notebook:/notebook -e ZEPPELIN_LOG_DIR='/l
