Solved: How to lock Terraform provider version

While working with terraform you would have noticed that every time you execute a terraform plan it will download the latest version of terraform available for that provider.
While this is good if you are testing as you get the latest features but, it can create trouble in production if a buggy version gets deployed. So, it is always recommended that you lock down the version of provider. In this post we will show you how to do that.
It’s really very simple to lock down the provider version. You just have to add a snippet like below in your main.tf file .

provider "aws" {
  version="<=2.6.0"
  region  = "us-east-1"
}

In the above example we have specified that version 2.6.0 or older can be used.
The version argument value may either be a single explicit version or a version constraint string. Constraint strings use the following syntax to specify a range of versions that are acceptable:
>= 2.4.0: version 2.4.0 or newer
<= 2.4.0: version 2.4.0 or older
~> 2.4.0: any non-beta version >= 2.4.0 and < 2.5.0, e.g. 2.4.X
~> 2.4: any non-beta version >= 2.4.0 and < 3.0.0, e.g. 2.X.Y
>= 2.0.0, <= 3.0.0: any version between 2.0.0 and 3.0.0 inclusive
