Custom environment variables for your deployment/application using secrets
The root360 platform does provide a default set of environment variables already, e.g. details about other components (databases, cache layers, filesystems and so on) or the current environment (test, stage, prod, ….). Using those environment variables via install.sh you can configure your application with the appropriate endpoints of the environment.
You can enhance or extend this list of variables by adding new items yourself using the https://root360.atlassian.net/wiki/spaces/KB/pages/2014350252. The content will be added to an encrypted vault inside AWS SecretsManager.
To verify the values on the targets you’re setting the secrets for, you can either run sudo get-application-env (see https://root360.atlassian.net/wiki/spaces/KB/pages/2014351825) on these roles when using EC2 instance deployment or r3 container deploy <params> --only-show-taskdefinition for container based workloads (see https://root360.atlassian.net/wiki/spaces/KB/pages/2014352658).
Variables already being provided by Managed AWS Hosting platform can’t be overwritten. Duplicate variable key names will be post-fixed with _CONFLICTING_KEY.
Preconditions
You need access to the environments jump host with your personal OpenSSH access key.
Secret value size must not exceed
64K(per secret)
List Secrets
List all available secrets.
~$ r3 secret list

| Name | LastChangedDate | LastAccessedDate |
+--------+----------------------------------+---------------------------+
| role_a | 2022-11-03 07:01:31.038000+00:00 | 2022-12-02 00:00:00+00:00 |

+--------+----------------------------------+---------------------------+Show Secrets
As the secrets scope is per role, you must provide a role parameter.
~$ r3 secret show --role=example
+-------------+-----------------------------------------------+
| Secret | Value |
+-------------+-----------------------------------------------+
| EXAMPLE_VAR | these-are-not-the-secrets-you-are-looking-for |
+-------------+-----------------------------------------------+Add/Update secrets
As the secrets scope is per role, you must provide a role parameter.
If you’re running container workloads using a secret and modify the secret you must re-deploy the affected service(s) to pick up the changes. If you don’t redeploy, ECS will keep your current containers with the old secret value and would start new containers using the new secret values.
You can use an interactive editor:
~$ r3 secret update --role=example --key=MYVAR --editor nano
... an editor window opens up, now paste your content and save the file...
2020-11-17 10:42:40 r3-11364 SUCCESS Secret "MYVAR" successfully updated.
+-------------+-----------------------------------------------+
| Secret | Value |
+-------------+-----------------------------------------------+
| EXAMPLE_VAR | these-are-not-the-secrets-you-are-looking-for |
| MYVAR | may-the-cloud-be-with-you |
+-------------+-----------------------------------------------+Complex values are supported by using a textfile:
Values can also be submitted directly (which should be avoided due to security concerns)
Delete secrets
As the secrets scope is per role, you must provide a role parameter.
If you’re running container workloads that are using a secret and delete the secret you must re-deploy the affected service(s) to pick up the changes. If you don’t redeploy ECS will fail to start new containers for services that used the secret.
Select specific secret for container deployment
For container workloads, you can share a secret between multiple services. This way you create a single secret to use for e.g. Frontend, Backend and Cron based on the same framework. Just specify --secret-name=<secret name> during deployment.
