--- layout: commands page_title: 'Commands: KV Get' --- # Consul KV Get Command: `consul kv get` Corresponding HTTP API Endpoint: [\[GET\] /v1/kv/:key](/api-docs/kv#read-key) The `kv get` command is used to retrieve the value from Consul's KV store at the given key name. If no key exists with that name, an error is returned. If a key exists with that name but has no data, nothing is returned. A key name or prefix is required. -> **Note**: When reading many entries under a given prefix, it may be worth considering [`kv export`](/commands/kv/export) instead. The kv export output can be used with [`kv import`](/commands/kv/import) to move entire trees between Consul clusters. Alternatively, the [transaction API](/api-docs/txn) provides support for performing up to 64 KV operations atomically. The table below shows this command's [required ACLs](/api#authentication). Configuration of [blocking queries](/api/features/blocking) and [agent caching](/api/features/caching) are not supported from commands, but may be from the corresponding HTTP endpoint. | ACL Required | | ------------ | | `key:read` | ## Usage Usage: `consul kv get [options] [KEY_OR_PREFIX]` #### API Options @include 'http_api_options_client.mdx' @include 'http_api_options_server.mdx' #### Enterprise Options @include 'http_api_namespace_options.mdx' @include 'http_api_partition_options.mdx' #### KV Get Options - `-base64` - Base 64 encode the value. The default value is false. - `-detailed` - Provide additional metadata about the key in addition to the value such as the ModifyIndex and any flags that may have been set on the key. The default value is false. - `-keys` - List keys which start with the given prefix, but not their values. This is especially useful if you only need the key names themselves. This option is commonly combined with the -separator option. The default value is false. - `-recurse` - Recursively look at all keys prefixed with the given path. The default value is false. - `-separator=` - String to use as a separator for recursive lookups. The default value is "/", and only used when paired with the `-keys` flag. This will limit the prefix of keys returned, only up to the given separator. ## Examples To retrieve the value for the key named "redis/config/connections" in the KV store: ```shell-session hideClipboard $ consul kv get redis/config/connections 5 ``` This will return the original raw value stored in Consul. If the key with the given name does not exist, an error is returned. ```shell-session hideClipboard $ consul kv get not-a-real-key Error! No key exists at: not-a-real-key ``` ### Detailed Output To view detailed information about the key, specify the `-detailed` flag. This will output all known metadata about the key including `ModifyIndex` and any user-supplied flags: ```shell-session hideClipboard $ consul kv get -detailed redis/config/connections CreateIndex 336 Flags 0 Key redis/config/connections LockIndex 0 ModifyIndex 336 Session - Value 5 ``` ### Recursively Reading By Prefix To treat the path as a prefix and list all entries which start with the given prefix, specify the `-recurse` flag: ```shell-session hideClipboard $ consul kv get -recurse redis/ redis/config/connections:5 redis/config/cpu:128 redis/config/memory:512 ``` Alternatively, combine with the `-detailed` flag to list detailed information about all entries under a prefix: ```shell-session hideClipboard $ consul kv get -recurse -detailed redis CreateIndex 336 Flags 0 Key redis/config/connections LockIndex 0 ModifyIndex 336 Session - Value 5 CreateIndex 472 Flags 0 Key redis/config/cpu LockIndex 0 ModifyIndex 472 Session - Value 128 CreateIndex 471 Flags 0 Key redis/config/memory LockIndex 0 ModifyIndex 471 Session - Value 512 ``` ### Listing Keys To just list the keys which start with the specified prefix, use the `-keys` option instead. This is more performant and results in a smaller payload: ```shell-session hideClipboard $ consul kv get -keys redis/config/ redis/config/connections redis/config/cpu redis/config/memory ``` By default, the `-keys` operation uses a separator of "/", meaning it will not recurse beyond that separator. You can choose a different separator by setting `-separator=""`. ```shell-session hideClipboard $ consul kv get -keys -separator="c" redis redis/c ``` Alternatively, you can disable the separator altogether by setting it to the empty string: ```shell-session hideClipboard $ consul kv get -keys -separator="" redis redis/config/connections redis/config/cpu redis/config/memory ``` To list all keys at the root, simply omit the prefix parameter: ```shell-session hideClipboard $ consul kv get -keys memcached/ redis/ ```
