For convenient switching between various AWS accounts within Google Chrome you can use the AWS Extend Switch Roles plugin.
Please download it here.
Use the following configuration as a start:
[myorg-master]
aws_account_id = ${MASTER_AWS_ACCOUNT_ALIAS}
[myorg-playground]
aws_account_id = ${PLAYGROUND_AWS_ACCOUNT_ID}
role_name = Administrator
color = 45C421
source_profile = myorg-master
[myorg-shared-services]
aws_account_id = ${SHARED_SERVICES_AWS_ACCOUNT_ID}
role_name = Administrator
color = 354B8C
source_profile = myorg-master
[myorg-log-archive]
aws_account_id = ${LOG_ARCHIVE_AWS_ACCOUNT_ID}
role_name = d9400d
color = C0403B
source_profile = myorg-master
[myorg-app-staging]
aws_account_id = ${APP_STAGING_AWS_ACCOUNT_ID}
role_name = Administrator
color = B88C14
source_profile = myorg-master
[myorg-app-prod]
aws_account_id = ${APP_PROD_AWS_ACCOUNT_ID}
role_name = Administrator
color = D9400D
source_profile = myorg-master
Use the account alias of the master account for ${MASTER_AWS_ACCOUNT_ALIAS}.
The alias will be shown in the role dropdown in the top bar after ‘Account:‘.
