Practice Exercise 1: Familiarizing yourself with the environment

Objectives

Familiarize yourself with the environment that we will use for the a1t-inf-ds course.

Tasks

  • SSH into your instance, connect to the bastion server then use the command below: 
    ssh <NAME>-a1t-inf-ds-web1.acad.opswerks.net
  • Alternatively you can also use the command below: 
     ssh -J <NAME>@bastion-1.acad.opswerks.net <NAME>@<NAME>-a1t-inf-ds-db2.acad.opswerks.net

When you use the -J flag, your SSH client first connects to the jump host, and from there, it establishes a connection to the destination host. 

ssh -J <jump_host> <destination_host>

Conclusion

You have now familiarized yourself with the environment with a refresher on common commands keep in mind on how to use SSH as this is an important command that we will be using throughout this course.
