[profile project1]
region = eu-west-1

~/.aws/credentials

[default]
aws_access_key_id = <Your AWS Access Key ID>
aws_secret_access_key = <Your AWS Secret Access Key>
[project1]
aws_access_key_id = <Your AWS Access Key ID>
aws_secret_access_key = <Your AWS Secret Access Key>

For further information how to setup your credentials see the offical AWS Userguide: AWS Command Line Interface - Configuration

ec2list Configuration

You can also configure the behavior of ec2list. Write your configuration file either in ~/.ec2list or ~/.aws/ec2list.

The configuration is processed and overwritten in this order:

coded default -> configfile 'default' section -> configfile 'profile' section -> commandline arguments

Following Options can be writen in your config file:

• region <- specific the region or multiple to list your instances
• view <- 'public' or 'private' - which view do you want on the instances.
• showtotal <- 'true' or 'false' - list all instances of multiple regions at once
• showhead <- 'true' or 'false' - show table head before listing your instances
• showbanner <- 'true' or 'false' - show program name before listing your instances
• clearscreen <- 'true' or 'false' - clear screen before listing your instances
• ttyrename <- 'true' or 'false' - rename your ssh session, useful if your are using multiple tabs

Here are some examples

[default]
ttyrename = true
clearscreen = true
view = private

[project1]
view = public
region = eu-west-1, eu-central-1

[project2]
view = private
region = eu-central-1

[project3]
view = private
region = us-west-*
showtotal = true
