To enable Azure repositories, you have first to define your azure storage settings as secure settings, before starting up the node:
bin/elasticsearch-keystore add azure.client.default.account bin/elasticsearch-keystore add azure.client.default.key
account is the azure account name and
key the azure secret key.
These settings are used by the repository’s internal azure client.
Note that you can also define more than one account:
bin/elasticsearch-keystore add azure.client.default.account bin/elasticsearch-keystore add azure.client.default.key bin/elasticsearch-keystore add azure.client.secondary.account bin/elasticsearch-keystore add azure.client.secondary.key
default is the default account name which will be used by a repository,
unless you set an explicit one in the
key storage settings are
reloadable. After you
reload the settings, the internal azure clients, which are used to transfer the
snapshot, will utilize the latest settings from the keystore.
In progress snapshot/restore jobs will not be preempted by a reload of the storage secure settings. They will complete using the client as it was built when the operation started.
You can set the client side timeout to use when making any single request. It can be defined globally, per account or both. It’s not set by default which means that Elasticsearch is using the default value set by the azure client (known as 5 minutes).
max_retries can help to control the exponential backoff policy. It will fix the number of retries
in case of failures before considering the snapshot is failing. Defaults to
The initial backoff period is defined by Azure SDK as
30s. Which means
30s of wait time
before retrying after a first timeout or failure. The maximum backoff period is defined by Azure SDK as
endpoint_suffix can be used to specify Azure endpoint suffix explicitly. Defaults to
cloud.azure.storage.timeout: 10s azure.client.default.max_retries: 7 azure.client.default.endpoint_suffix: core.chinacloudapi.cn azure.client.secondary.timeout: 30s
In this example, timeout will be
10s per try for
7 retries before failing
and endpoint suffix will be
30s per try for
Supported Azure Storage Account types
The Azure Repository plugin works with all Standard storage accounts
- Standard Locally Redundant Storage -
- Standard Zone-Redundant Storage -
- Standard Geo-Redundant Storage -
- Standard Read Access Geo-Redundant Storage -
Premium Locally Redundant Storage (
Premium_LRS) is not supported as it is only usable as VM disk storage, not as general storage.
You can register a proxy per client using the following settings:
azure.client.default.proxy.host: proxy.host azure.client.default.proxy.port: 8888 azure.client.default.proxy.type: http
Supported values for
proxy.type is set to
proxy.port must be provided.
