It is capable of distributing new encryption keys to the 11 cluster, retiring old encryption keys, and changing the keys used by the cluster 12 to encrypt messages. 13 14 Nomad allows multiple encryption keys to be in use simultaneously. This is 15 intended to provide a transition state while the cluster converges. It is the 16 responsibility of the operator to ensure that only the required encryption keys 17 are installed on the cluster. You can review the installed keys using the 18 `-list` argument, and remove unneeded keys with `-remove`. 19 20 All operations performed by this command can only be run against server nodes 21 and will effect the entire cluster. 22 23 All variations of the `keyring` command return 0 if all nodes reply and there 24 are no errors. If any node fails to reply or reports failure, the exit code 25 will be 1. 26 27 ## Usage 28 29 ```plaintext 30 nomad operator keyring [options] 31 ``` 32 33 Only one actionable argument may be specified per run, including `-list`, 34 `-install`, `-remove`, and `-use`. 35 36 The list of available flags are: 37 38 - `-list` - List all keys currently in use within the cluster. 39 40 - `-install` - Install a new encryption key. This will broadcast the new key to 41 all members in the cluster. 42 43 - `-use` - Change the primary encryption key, which is used to encrypt messages. 44 The key must already be installed before this operation can succeed. 45 46 - `-remove` - Remove the given key from the cluster. This operation may only be 47 performed on keys which are not currently the primary key. 48 49 ## Output 50 51 The output of the `nomad operator keyring -list` command consolidates 52 information from all the Nomad servers from all datacenters and regions to 53 provide a simple and easy to understand view of the cluster. 54 55 ```shell-sessionnomad operator keyring -list 56 ==> Gathering installed encryption keys... 57 Key 58 PGm64/neoebUBqYR/lZTbA== 59 ```
