mounting AWS (Amazon Web Services) EFS on Linux Ubuntu 18.04

Amazon Elastic File System (Amazon EFS) is a scalable file storage for EC2 and services that run on EC2 (for example Kubernetes clusters). The device is accessible on Linux via the NFS protocol and can be used my multiple instances and pods at the same time. For more information on EFS visit AWS documentation. Step one: Gather information In our case ti is pretty straightforward. Ubuntu instance in the same VPC as the EFS and a DNS name of the file system we want to access. The format uses following convention: And the exact URL is available on AWS console AWS home under filesystem's DNS name or via cli Step two: Install the NFS Client for Linux $  sudo apt-get update $  sudo apt install nfs-kernel-server Step three: Mount the file system on EC2 instance. Create (if you don't have already) a mount point for the EFS $  sudo mkdir -p /mnt/efs-mount-point Mount the EFS share on the instance $  sudo mount -t

How to Install Terraform 0.12 on Ubuntu 18.04

To this day (8/8/2019) Terraform is not packaged in an official apt repository. There is an option to install it with Snap but be careful it will probably be an older version. When i checked it was v0.11.11 If you do want to install it with snap, run: $   snap install terraform To install the latest version follow this procedure. You might want to update your system just in case: $  sudo apt-get update Now since you are getting a Terraform binary from official Hashicorp site, you will need both wget and unzip packages unless already installed: $  sudo apt-get install wget unzip Last step would be to download an unzip Terraform package ( you can find latest here ). $  wget $  sudo unzip ./ -d /usr/local/bin/ check that it is installed: $ terraform -v you are all done.
