LSST SQuaRE Vault utilities

LSST Vault Utilities

This package is a set of Vault utilities useful for the LSST use case.

LSST Vault Hierarchy

These tools are intended to work with a specific taxonomic hierarchy, detailed below.

Secrets

The primary use case for the LSST vault has been to act as a repository for Kubernetes secrets. Those are organized as follows:

secret/k8s_operator/:instance:

These secrets are typically created and injected at cluster creation time; in the case of the LSP deployment, this is scripted.

The secondary, more flexible, use case is to use the LSST vault as a generalized key-value store.

The current plan is for the LSST vault to be organized with secrets under secret as follows:

secret/:subsystem:/:team:/:category:/:instance:

As an example, secrets for the nublado.lsst.codes instance of the LSST Science Platform Notebook Aspect are stored in secret/dm/square/nublado/nublado.lsst.codes. Underneath that there are hub, proxy, and tls secret folders, each of which has a number of individual secrets, e.g. secret/dm/square/nublado/nublado.lsst.codes/hub/oauth_secret.

Note that these secrets are not accessible to the administrative user that created the token pair and policies. They are accessed through one of those tokens.

We assume that each secret has its own folder, whose name is the secret key, inside of which the keyname is value. This makes translating back and forth between Vault secrets and Kubernetes secrets (which have multiple key-value pairs) much easier.

Tokens

The first thing to do, with an administrative token, is to create a delegator token which will be the token used to run the Vault token provisioning tools. Use delegator.hcl as the input to create a policy for this. Then create a token with that new delegator policy attached.

Token IDs and accessors are stored under secret/delegated/:subsystem:/:team:/:category:/:instance:/:role:/:type: where role is one of read or write and type is one of id or accessor. These secrets are only accessible to an administrative user (such as the one that created the token pair in the first place, which should be the token attached to the delegator policy created above).

There are two tokens for each path, comprising the "token pair". These are read and write.

It is our intention that a runtime system have access to the read token to be able to read (but not update) secrets, and that the administrators of such a system have access to the write token to create, update, and remove secrets. We have provided a tool that allows easy copying of Kubernetes secrets to and from Vault.

Policies

Policies are stored as delegated/:subsystem:/:team:/:category:/:instance:/:role: where role is one of read or write. The administrative user that creates or revokes the token pair is also responsible for creating and destroying these policies.

Classes

The package name is lsstvaultutils. Its functional classes are:

1. SecretCopier -- this copies secrets between the current Kubernetes context and a Vault instance.

2. AdminTool -- this highly LSST-specific class allows you to specify a path under the Vault secret store, and it will generate two tokens (read and write) for manipulating secrets under the path. It stores those under secret/delegated, so that an admin can find (and, if need be, revoke) them later. It also manages revoking those tokens and removing them from the secret/delegated path. Options exist to, if manipulating tokens on a path that already exist, revoke the old tokens and overwrite with new ones, or to remove the secret data at the same time as the tokens are revoked. There is also a function to display the IDs and accessors of the token pair associated with the path.

3. RecursiveDeleter -- this adds a recursive deletion feature to Vault for removing a whole secret tree at a time.

There is also a TimeFormatter class that exists only to add milliseconds to the debugging logs. There is a convenience function, getLogger, that provides an interface to get a standardized logger for these tools and classes.

Programs

The major functionality of these classes is also exposed as standalone programs.

1. copyk2v -- copy the contents of a Kubernetes secret to a Vault secret path.

2. copyv2k -- copy a set of Vault secrets at a specified path to a Kubernetes secret.

3. tokenadmin -- Create or revoke token sets for a given Vault secret path, or display the token IDs and accessors for that path.

4. vaultrmrf -- Remove a Vault secret path and everything underneath it. As is implied by the name, this is a fairly dangerous operation.

Example Workflow

We will go through a workflow that exercises all of the standalone programs, by creating a token pair, creating some secrets, copying the secrets from Vault to Kubernetes and back again, deleting a secret tree, and finally deleting the token pair.

Create a token pair.

First we'll create a token pair for a hierarchy at dm/test. (Note that we have omitted a level of hierarchy to make the output slightly more readable; dm/square/test would be more realistic.) We ensure that VAULT_ADDR and VAULT_CAPATH are set correctly, and that VAULT_TOKEN is set to an appropriate administrative token. We're going to use debug to get an idea of what's going on during the process, and we will use the display option to print JSON representing the tokens.

I am using a vaultutils virtualenv with the lsstvaultutils package installed, and the vault CLI is on my path.

{
    "dm/test": {
        "read": {
            "accessor": "1WRccTQEebkqx78t37EyVztK",
            "id": "s.3nyTeqdWiINKIKNtuoIDtD9D"
        },
        "write": {
            "accessor": "8LvOhKiGFJf9qYNIgOXrb8Ik",
            "id": "s.4l4eDdLMyD436RsjRqlI11cD"
        }
    }
}

Add some secrets

First, set Vault to use the write token:

export VAULT_TOKEN="s.4l4eDdLMyD436RsjRqlI11cD"

I like JSON output, so I'm going to set:

export VAULT_FORMAT=json

Then use the vault client to add some secrets:

(vaultutils) adam@ixitxachitl:~$ vault kv put secret/dm/test/group1/foo value=bar
{
  "request_id": "0a814bd2-e95d-cf1c-9018-c00173668e3d",
  "lease_id": "",
  "lease_duration": 0,
  "renewable": false,
  "data": {
    "created_time": "2019-03-04T21:51:07.616034224Z",
    "deletion_time": "",
    "destroyed": false,
    "version": 1
  },
  "warnings": null
}
(vaultutils) adam@ixitxachitl:~$ vault kv put secret/dm/test/group1/baz value=quux
{
  "request_id": "38c65e0d-735d-db9a-c2d6-840bdd4dff65",
  "lease_id": "",
  "lease_duration": 0,
  "renewable": false,
  "data": {
    "created_time": "2019-03-04T21:51:34.991913644Z",
    "deletion_time": "",
    "destroyed": false,
    "version": 1
  },
  "warnings": null
}
(vaultutils) adam@ixitxachitl:~$ vault kv put secret/dm/test/group2/king value=fink
{
  "request_id": "12753857-25f2-a27a-3d65-badc18805d07",
  "lease_id": "",
  "lease_duration": 0,
  "renewable": false,
  "data": {
    "created_time": "2019-03-04T21:51:45.645224365Z",
    "deletion_time": "",
    "destroyed": false,
    "version": 1
  },
  "warnings": null
}

Read one back:

(vaultutils) adam@ixitxachitl:~$ vault kv get secret/dm/test/group1/baz
{
  "request_id": "03ef8ba1-3eb2-2962-d4c6-ebaf595e3387",
  "lease_id": "",
  "lease_duration": 0,
  "renewable": false,
  "data": {
    "data": {
      "value": "quux"
    },
    "metadata": {
      "created_time": "2019-03-04T21:51:34.991913644Z",
      "deletion_time": "",
      "destroyed": false,
      "version": 1
    }
  },
  "warnings": null
}

Copy secrets to Kubernetes

Now let's create Kubernetes secrets from these. Do whatever you need to do in order to get a current authenticated Kubernetes context.

Switch to the read token--we don't need to use a write token to copy from Vault to Kubernetes. The Kubernetes user must be able to create secrets, of course, but that's got nothing to do with Vault tokens.

export VAULT_TOKEN="s.3nyTeqdWiINKIKNtuoIDtD9D"

Then we'll copy a set of secrets from Vault to Kubernetes:

(vaultutils) adam@ixitxachitl:~$ copyv2k --debug dm/test/group1 testg1
2019-03-04 14:54:52.855 MST(-0700) [DEBUG] lsstvaultutils.secretcopier | Debug logging started.

2019-03-04 14:54:53.971 MST(-0700) [DEBUG] lsstvaultutils.secretcopier | Updating secret.

Repeat the process for the second group; we'll omit --debug this time.

(vaultutils) adam@ixitxachitl:~$ copyv2k dm/test/group2 testg2
(vaultutils) adam@ixitxachitl:~$

Now let's see if the copy worked.

(vaultutils) adam@ixitxachitl:~$ kubectl get secret -o yaml testg2
apiVersion: v1
data:
  king: Zmluaw==
kind: Secret
metadata:
  creationTimestamp: 2019-03-04T21:55:47Z
  name: testg2
  namespace: nublado
  resourceVersion: "10389477"
  selfLink: /api/v1/namespaces/nublado/secrets/testg2
  uid: 445509ca-3ec8-11e9-a1ce-42010a800032
type: Opaque

Decode that secret:

(vaultutils) adam@ixitxachitl:/tmp$ echo -n Zmluaw== | base64 -D -
fink

Copy secret from Kubernetes to Vault

Go back to the "write" token:

export VAULT_TOKEN="s.4l4eDdLMyD436RsjRqlI11cD"

Copy the secret to a new Vault path:

(vaultutils) adam@ixitxachitl:~$ copyk2v testg1 dm/test/copy1
(vaultutils) adam@ixitxachitl:~$

Read a value (we could switch to the Vault read token, but we don't have to--write is also allowed to read) back:

(vaultutils) adam@ixitxachitl:/tmp$ vault kv get secret/dm/square/copy1/foo
{
  "request_id": "7a509ffc-eaf6-ee43-0d6b-d6bc4fe08a8b",
  "lease_id": "",
  "lease_duration": 0,
  "renewable": false,
  "data": {
    "data": {
      "value": "bar"
    },
    "metadata": {
      "created_time": "2019-03-04T22:01:57.690906156Z",
      "deletion_time": "",
      "destroyed": false,
      "version": 1
    }
  },
  "warnings": null
}

Recursively remove a secret tree

Let's say we didn't really want to do that last copy. We can easily remove the tree.

Then we can use the vaultrmrf command (and the write token) to delete the tree.

(vaultutils) adam@ixitxachitl:~$ vaultrmrf --debug dm/test/copy1

Trying to read the secret now will show it's gone:

(vaultutils) adam@ixitxachitl:~$ vault kv get secret/dm/test/copy1/foo
No value found at secret/data/dm/test/copy1/foo

Revoke Token Pair and remove data

Now we will clean up:

(vaultutils) adam@ixitxachitl:~$ kubectl delete secret testg1 testg2
secret "testg1" deleted
secret "testg2" deleted

We go back to an administrative token to revoke our token pair (by setting VAULT_TOKEN to an appropriate value), and while we're at it we will clean up the data we inserted into vault as well.

Verifying token deletion

We can try an operation to see that the tokens have been revoked. Set up the (now-revoked) read token: export VAULT_TOKEN="s.3nyTeqdWiINKIKNtuoIDtD9D". Then try the same read we previously ran again:
