SNMPv3 secrets¶
Creating a secret requires updating configuration of several docker compose files. To simplify this process, inside the
docker_compose package there is a manage_secrets.py file which will automatically manage secrets.
Creating a new secret¶
To create a new secret, manage_secrets.py must be run with the following flags:
| Flag | Description |
|---|---|
--secret_name |
New secret name |
--path_to_compose |
Absolute path to directory with docker compose files |
--worker_poller |
[OPTIONAL] Add new secrets to worker poller. Default value is set to ‘true’. |
--traps |
[OPTIONAL] Add new secrets to traps server. Default value is set to ‘true’. |
--userName |
SNMPv3 userName |
--privProtocol |
SNMPv3 privProtocol |
--privKey |
SNMPv3 privKey |
--authProtocol |
SNMPv3 authProtocol |
--authKey |
SNMPv3 authKey |
--contextEngineId |
[OPTIONAL] SNMPv3 engine id |
This script, apart from updating configuration files, creates environmental variables with values of the secret at the
end of the .env file in the docker_compose directory. To apply those secrets run the
sudo docker compose $(find docker* | sed -e 's/^/-f /') up -d command inside the docker_compose directory. After execution of the command, plain text secrets
from the .env file can be deleted.
NOTE: In case of any changes in
.env, the secrets must be recreated by deleting any previously existing secrets and creating them once again. Changes in.envinclude creating new secrets.
Example of creating a secret¶
python3 <path_to_manage_secrets.py> --path_to_compose <path_to_compose> \
--secret_name my_secret \
--userName r-wuser \
--privProtocol AES \
--privKey admin1234 \
--authProtocol SHA \
--authKey admin1234 \
--contextEngineId 090807060504037
Inside docker_compose directory run:
sudo docker compose $(find docker* | sed -e 's/^/-f /') up -d
Now, the following lines from the .env can be deleted:
my_secret_userName=r-wuser
my_secret_privProtocol=AES
my_secret_privKey=admin1234
my_secret_authProtocol=SHA
my_secret_authKey=admin1234
my_secret_contextEngineId=090807060504037
Deleting a secret¶
To delete a secret, manage_secrets.py must be run with the following flags:
| Flag | Description |
|---|---|
--secret_name |
Secret name |
--path_to_compose |
Absolute path to directory with docker compose files |
--delete |
Set this flag to true to delete the secret |
This will delete the secret with a given name from all docker compose files. If this secret hasn’t been deleted from .env
file, it will be removed from there.
Example of deleting a secret¶
python3 <path_to_manage_secrets.py> --path_to_compose <path_to_compose> \
--secret_name my_secret \
--delete true
