Background

I automate, develop and maintain a lot of Vault cluster for different clients. When automating Vault using tools such as terraform and ansible I was missing a small utility that allows me to quickly perform certain operations like generate a new root token or create a snapshot. Thus I came up with vops, which stands for vault-operations

Quickstart

Prerequisites

Start a Vault with Integrated Storage locally:

mkdir raft
cat <<EOF > vault-cfg.hcl
cluster_addr = "http://127.0.0.1:8201"
api_addr = "http://127.0.0.1:8200"

storage "raft" {
  path = "./raft"
  node_id = "node"
}

ui = true

listener "tcp" {
  address = "0.0.0.0:8200"
  tls_disable = true
}
EOF
vault server -config=vault-cfg.hcl

vops.yaml

In another Terminal create a vops.yaml example config:

vops config example > vops.yaml
cat vops.yaml

created the following vops.yaml:

Cluster:
  - Name: cluster-1
    Addr: http://127.0.0.1:8200
    TokenExecCmd: jq -r '.root_token' {{ .Keys.Path }}
    Keys:
      Path: '{{ .Name }}.json'
      Shares: 1
      Threshold: 1
    SnapshotDirectory: '{{ .Name }}/'
    Nodes:
      - '{{ .Addr }}'
    ExtraEnv:
      VAULT_TLS_SKIP_VERIFY: true
CustomCmds:
  list-peers: vault operator raft list-peers
  status: vault status

List Cluster

lists all defined clusters and validates their settings, performs a vault login

$> vops config validate      
[ Validate ]
using ./assets/vops.yaml

Name:                   cluster-1
Address:                http://127.0.0.1:8200
TokenExecCmd:           jq -r '.root_token' cluster-1.json
TokenExecCmd Policies:  [root]
Nodes:                  [http://127.0.0.1:8200]
Key Config:             {Path: cluster-1.json, Shares: 5, Threshold: 5}
Snapshot Directory:     snapshots/

Initialize

initialize vault cluster

$> vops init -c <cluster>
[ Intialization ]
using vops.yaml

[ cluster-1 ]
attempting intialization of cluster "cluster-1" with 1 shares and a threshold of 1
applying VAULT_TLS_SKIP_VERIFY
successfully initialized cluster-1 and wrote keys to cluster-1.json.

Tip: You can also specify the cluster by providing a environment variable named VOPS_CLUSTER or run the command for all cluster using -A or --all-cluster.

Unseal

unseal a vault cluster using the specified keyfile

> vops unseal -c <cluster>
[ Unseal ]
using vops.yaml

[ cluster-1 ]
applying VAULT_TLS_SKIP_VERIFY
using keyfile "cluster-1.json"
unsealing node "http://127.0.0.1:8200"
cluster "cluster-1" unsealed

Seal

seal a cluster

> vops seal -c <cluster>
[ Seal ]
using vops.yaml

[ cluster-1 ]
applying VAULT_TLS_SKIP_VERIFY
executed token exec command
cluster "cluster-1" sealed

Rekey

generates new unseal/recover keys

> vops rekey -c <cluster>
[ Rekey ]
reading ./assets/vops.yaml

[ cluster-1 ]
performing a rekey for cluster-1 with 5 shares and a threshold of 3
applying VAULT_SKIP_VERIFY
using keyfile "cluster-1.json"
initialized rekey process
[01/03] successfully entered key
[02/03] successfully entered key
[03/03] successfully entered key
rekeying successfully completed
renamed keyfile "cluster-1.json" for cluster "cluster-1" to "cluster-1_2023-03-10-16:05:16.json".
Hint: snapshots depend on the unseal/recovery keys from the moment the snapshot has been created.
This way you always have the matching unseal/recovery keys for the specific snapshot if needed ready.

Generate Root

generates a new root token

> vops generate-root -c <cluster>
[ Generate Root Token ]
using vops.yaml

[ cluster-1 ]
applying VAULT_TLS_SKIP_VERIFY
generated on OTP for root token creation
started root token generation process
root token generation completed
new root token: "hvs.dmhO9aVPT0aBB1G7nrj3UdDh" (make sure to update your token exec commands in your vops configfile if necessary.)

Snapshots

Snapshot save

creates a snapshot and stores the corresponding keyfile with it (only integrated storage)

> vops snapshot save -c <cluster>
[ Save ]
reading ./assets/vops.yaml

[ cluster-1 ]
applying VAULT_SKIP_VERIFY
executed token exec command
created snapshot file "snapshots/cluster-1_2023-03-10-16:03:38.gz" for cluster "cluster-1"
created snapshot keyfile "snapshots/cluster-1_2023-03-10-16:03:38_keyfile.json" for cluster "cluster-1"

Snapshot Restore

restores a snapshot (only integrated storage)

> vos snapshot restore -c <cluster> -s <snapshot-file>
[ Restore ]
reading ./assets/vops.yaml

[ cluster-1 ]
applying VAULT_SKIP_VERIFY
executed token exec command
restrored snapshot for cluster-1
Remember to use the root token und unseal/recovery keys from the snapshot you just restored    

Custom Commands

You can run any defined custom commands:

> vops custom --list
[ Custom ]
using vops.yaml

[ Available Commands ]
"list-peers": "vault operator raft list-peers"
"status": "vault status"

run any available command with "vops custom -x <command name> -c <cluster-name>".

> vops custom -x <custom command> -c <cluster>

using vops.yaml

[ cluster-1 ]

UI

opens the Vault Address in your default browser

vops ui -c <cluster>
[ UI ]
using ./assets/vops.yaml

[ cluster-1 ]
opening http://127.0.0.1:8200

Login

performs a vault token login command in order to work with the vault CLI

vops login -c <cluster>
[ Login ]
using ./assets/vops.yaml

[ cluster-1 ]
performing a vault login to http://127.0.0.1:8200
applying VAULT_SKIP_VERIFY
applying VAULT_TLS_CA
applying VAULT_ADDR
applying VAULT_TOKEN
executed token exec command

$> vault login $(jq -r '.root_token' cluster-1.json)
Success! You are now authenticated. The token information displayed below
is already stored in the token helper. You do NOT need to run "vault login"
again. Future Vault requests will automatically use this token.

Key                  Value
---                  -----
token                hvs.5aYsklTzIYR26iWRttqFoCm1
token_accessor       R7l5fidrohVB5Tc4pXBcUtoO
token_duration       ∞
token_renewable      false
token_policies       ["root"]
identity_policies    []
policies             ["root"]

Token

copy the token from the token exec command to your clipboard buffer

vops token -c <cluster>

[ Token ]
using ./assets/vops.yaml

[ cluster-1 ]
copying token for cluster cluster-1
applying VAULT_SKIP_VERIFY
applying VAULT_TLS_CA
applying VAULT_ADDR
applying VAULT_TOKEN
token for cluster cluster-1 copied to clipboard buffer.

About the Key.Path-file

for now, vops expect the JSON format output from a vault operator init command:

{
  "unseal_keys_b64": [
    "YrnZCLIdwKDNn9RYkUx3A7J9/I4ogORIXYcTtJ/AWtg="
  ],
  "unseal_keys_hex": [
    "62b9d908b21dc0a0cd9fd458914c7703b27dfc8e2880e4485d8713b49fc05ad8"
  ],
  "unseal_shares": 1,
  "unseal_threshold": 1,
  "recovery_keys_b64": [],
  "recovery_keys_hex": [],
  "recovery_keys_shares": 0,
  "recovery_keys_threshold": 0,
  "root_token": "hvs.EhCMSSb1uCW1y0aHI1IZ3feO"
}

Later you can also just list the unseal/recovery keys in the vops.yml aswell, or specifiy pgp encrypted key files.
