Kviklet

Kviklet.dev | Release Notes

Secure access to production environments without impairing developer productivity.

Kviklet utilizes the Four-Eyes Principle and a high level of configurability, to allow a Pull Request-like Review and Approval flow for individual SQL statements or Database sessions. This allows engineering teams to self regulate on who gets access to what data and when.

Kviklet is a self hosted docker container, that provides you with a Single Page Web app that you can login to create your SQL requests or approve the ones of others.

We currently support Postgres, MySQL and MS SQL Server. Additionally we have a kubernetes shell integration that allows to run kubectl exec commands on pods.

Features

Kviklet ships with a variety of features that an engineering team needs to manage their production database access in a simple but secure manner:

• SSO (Google): Log into Kviklet without the need for a username or password. No more shared credentials for DB access.
• Review/Approval Flow: Leave Comments and Suggestions on other developers data requests.
• Temporary Access (1h): Execute any statement on a db for 1h after having been approved
• Single Query: Execute a singular statement. Allows the reviewer to review your query before execution.
• Auditlog: Singular plane that logs all executed statements with Author, reason for execution etc.
• RBAC: Configure which team has access to which database/table to as fine of a granularity as the DB Engine allows.
• Postgres Proxy: Start a proxy server to use the DB Client of your choice, but everything will be stored in the Kviklet Auditlog.
• Kubernetes Exec: Execute a statement on a pod in your kubernetes cluster. (Currently only supports Execution of a single command no live session yet)
• And more...

Setup

Kviklet ships as a simple docker container. You can find the available verions under Releases. We recommend to regularly update the version you are using as we continue to build new features.
The latest one currently is ghcr.io/kviklet/kviklet:0.3.0, you can also use :main but it might happen every now and then that we accidentally merge something buggy alhtough we try to avoid that.

DB Setup

Kviklet needs it's own database (or at least schema) to save metadata about queries, connections, approvals, etc. In theory you can setup a MySQL or Postgres DB for this purpose, we internally only use postgres though, so this is the recommended path.

When starting the container you then need to set these three environment variables:

SPRING_DATASOURCE_PASSWORD = password
SPRING_DATASOURCE_USERNAME = username
SPRING_DATASOURCE_URL = jdbc:postgresql://[host]:[port]/[database]?currentSchema=[schema]

Initial User

You will need an intial admin user for configuration purposes. For this set the 2 env variables: INITIAL_USER_EMAIL and INITIAL_USER_PASSWORD so that you can login into the web interface. You can change the password afterwards via the UI.
Example:

INITIAL_USER_EMAIL=admin@example.com
INITIAL_USER_PASSWORD=someverysecurepassword

We publish our containers do the github packages for now, so with all this set you can run ghcr.io/kviklet/kviklet:main don't forget to expose port 80.

An example docker run could looks like this:

docker run \
-e SPRING_DATASOURCE_PASSWORD=postgres \
-e SPRING_DATASOURCE_USERNAME=postgres \
-e SPRING_DATASOURCE_URL=jdbc:postgresql://localhost:5432/Kviklet \
-e INITIAL_USER_EMAIL=admin@example.com \
-e INITIAL_USER_PASSWORD=someverysecurepassword \
--network host \
ghcr.io/kviklet/kviklet:main

Google SSO

If you want to setup SSO for your Kviklet instance (which makes a lot of sense since otherwise you have to manage passwords again). You need to setup these 3 environment variables:

KVIKLET_IDENTITY_PROVIDER_CLIENT_ID
KVIKLET_IDENTITY_PROVIDER_CLIENT_SECRET
KVIKLET_IDENTITY_PROVIDER_TYPE=google

The google client id and secret you can easily get by following google instructions here: https://developers.google.com/identity/gsi/web/guides/get-google-api-clientid

For valid redirect URIs, you should configure: http://[kviklet_host]/api/login/oauth2/code/google For Allowed Origins, simply your hosted kviklet url.

After setting those environment variables everyone in your organization can login with the sign in with google button. But they wont have any permissions by default, you will have to assign them a role after they log in once.

Keycloak SSO

If you want to setup SSO with Keycloak instead you need to set these 4 environment variables:

KVIKLET_IDENTITY_PROVIDER_CLIENT_ID
KVIKLET_IDENTITY_PROVIDER_CLIENT_SECRET
KVIKLET_IDENTITY_PROVIDER_TYPE=keycloak
KVIKLET_IDENTITY_PROVIDER_ISSUER_URI=http://[host]:[port]/realms/[realm]

You get the client id and secret when you create an application in keycloack. For valid redirect URIs, you should configure: http://[kviklet_host]/api/login/oauth2/code/google For Allowed Origins, simply your hosted kviklet url.

After setting those environment variables the login page should show a Login with Keycloak button that redirects to your keycloak instance. We do currently not support role sync yet so you will have to manage roles directly in kviklet manually for now.

Kubernetes Exec

If you want to use the Kubernetes Exec feature you have to create a separate kubernetes connection. Kviklet will use the user of the deployed pod to execute the command. So make sure that the user has the necessary permissions to execute commands on the pods that you want to access.

Kviklet also uses /bin/sh to execute the command, so you will need to make sure your pods have a shell or at least a symlink in /bin/sh. If this bothers you feel free to open an issue, we can potentially make this configurable or find another solution.

Kubernetes commands only wait for 5 seconds for output if the command takes longer than that Kviklet will wait for up to an hour before timing out the command. This is a a provisional solution, we are looking into websockets to make this more responsive and potentially enable terminal sessions.

Proxy (Beta), Postgres only

If you create requests for temporary access. You can instead of using the web interface to run queries also enable a proxy and use the DB client of your choice. For this the container uses ports 5438-6000 so you need to expose those. The user can then create a temp access request, and click "Start Proxy" once it's been approved. They will get a port and a user + temporary password. With this they can login to the database. Kviklet validates the temp user and password and proxies all requests to the underlying user on the database. Any executed statements are logged in the auditlog as if they were run via the web interface.

Configuration

Connections

After starting Kviklet you first have to configure a database connection. Go to Settings -> Databases -> Add Connection.

Here you can configure how many reviews are required to run Requests on this connection. You can also configure how often a request can be run. The default is 1 and we recommend to stick to this for most use cases. As a special config, setting this to 0 any request on the connection can be run an infinite amount of times.

Roles

Kviklet ships with 2 default roles, Admins and Developers.

• Admins have the permission to create and edit connections, as well as adding new Users and setting their permissions.
• Developers can create Requests as well as approve and comment on them and ofcourse execute the actual statements.

You can completely customize Roles and e.g. give a role only access to a specific connection or a group of db connections. The UI for this is a bit clunky right now, but we are working on improving this for 0.4.0.
