vault-manager

vault-manager is an automation tool for managing hashicorp vault configurations based on Vault GO API Client

how to use

docker run --rm -t \
           -v <PATH_TO_FILE_WITH_GRAPHQL_QUERY>:/query.graphql \
           -e GRAPHQL_QUERY_FILE=/query.graphql \
           -e GRAPHQL_SERVER=<GRAPHQL_SERVER_URL> \
           -e GRAPHQL_USERNAME=<GRAPHQL_USERNAME> \
           -e GRAPHQL_PASSWORD=<GRAPHQL_PASSWORD> \
           -e VAULT_ADDR=<VAULT_INSTANCE_URL> \
           -e VAULT_AUTHTYPE=approle \
           -e VAULT_ROLE_ID=<APPROLE_ROLE_ID> \
           -e VAULT_SECRET_ID=<APPROLE_SECRET_ID> \
           quay.io/app-sre/vault-manager:latest -dry-run

Note that running vault-manager with -dry-run flag will only print planned actions, remove this flag to make changes enter into effect

Flags

• -dry-run, default=false
  runs vault-manager in dry-run mode and only print planned actions
• -thread-pool-size, default=10
  Some operations are running in parallel to achieve the best performance, so -thread-pool-size determine how many threads can be utilized

Changing data.json used for testing

data.json within tests/app-interface is utilized by the qontract-server created for testing. If schema / query changes are made, this data bundle must be re-generated and committed with the PR. To re-generate: update SCHEMAS_IMAGE_TAG within .env (make sure to commit this change as well) and execute make data within /tests/app-interface

Local Development

For local development, the script /local-dev.sh can be ran to configure necessary resources to mirror testing performed within PR check builds.

Once the script completes, the following containers will be running:

• keycloak
  • necessary for oidc testing
  • view /tests/keycloak for configuration files applied to the instance
• qontract-server
  • view /tests/app-interface/data/services/vault/config for all resources being reconciled by tests
• primary vault instance
  • running on localhost:8200
• secondary vault instance
  • running on localhost:8202

From root of repo, run source dev-env

You can now execute run vault-manager against the local vault instances. Note that after a non -dry-run, the resources will be added to the vault instances. To reset, simply rerun local-dev.sh

Note: --net=host isn't supported for Mac(doc). So if you are developing from Mac, remove the flag from local-dev.sh and also remove key-cloak related docker run command.

Example launch.json for VS Code:

{
    "version": "0.2.0",
    "configurations": [
      {
        "name": "Launch Package",
        "type": "go",
        "request": "launch",
        "mode": "auto",
        "program": "${workspaceFolder}/cmd/vault-manager/main.go",
        "args": ["--dry-run"],
        "env": {
          "VAULT_ADDR": "http://127.0.0.1:8200",
          "VAULT_TOKEN": "root",
          "VAULT_AUTHTYPE": "token",
          "GRAPHQL_SERVER": "http://localhost:4000/graphql",
          "GRAPHQL_QUERY_FILE": "/Users/olivia/SourceCode/app-sre/vault-manager/query.graphql"
        }
      }
    ]
  }

Testing:

This project use BATS for integration test, using mentioned primary and secondary vault instance. You can debug them by point environment variable GRAPHQL_QUERY_FILE to the .graphql under /fixtures.

Gotchas

Approle output_path

You will notice that the first -dry-run execution after spinning up environment will fail stating a specified output path does not match existing KV engines. This is due to how the tests within /tests/run-tests.sh are executed.
To resolve you can either:

a) manually create the app-interface secret engine for both vault instances

b) remove output_path from the following files:

• /tests/app-interface/data/services/vault/config/roles/master/approles/vault-manager.yml
• /tests/app-interface/data/services/vault/config/roles/secondary/approles/app-interface.yml
• update data.json following directions above do not commit data.json with these attributes missing

Vault audit device

Depending on local container runtime, permission issues when attempting to reconcile the vault audit devices may be encountered. If your development is not affecting logic within /toplevel/audit.go, you can remove the files within /tests/app-interface/data/services/vault/config/audit-backends and re-generate the data.json. do not commit data.json with these attributes missing
