Template anatomy A template is a JSON- or YAML-formatted text file that describes your AWS infrastructure. The following examples show an AWS CloudFormation template structure and its sections.

AWS::EC2::InstanceSpecifies an EC2 instance.

If an Elastic IP address is attached to your instance, AWS CloudFormation reattaches the Elastic IP address after it updates the instance. For more information about updating stacks, see AWS CloudFormation Stacks Updates.

CF-Conditions The optional Conditions section contains statements that define the circumstances under which entities are created or configured.

CF-Resources The required Resources section declares the AWS resources that you want to include in the stack, such as an Amazon EC2 instance or an Amazon S3 bucket.

AWS resource and property types reference This section contains reference information for all AWS resource and property types that are supported by AWS CloudFormation.

We often need to go into the container to do some work, such as viewing logs, debugging, starting other processes, etc. There are two ways to enter a container: attach and exec.

Docker Attach vs Exec The main differences between attach and exec are as follows: attach goes directly to the terminal of the container startup command and does not start a new process. exec opens a new terminal in the container and can start a new process.
