mc admin update
Description
The mc admin update command updates all MinIO servers
in the deployment. The command also supports using a private mirror
server for environments where the deployment does not have public
internet access.
Use mc admin on MinIO Deployments Only
Considerations
Updates are Non-Disruptive
mc admin update
updates the binary and restarts all MinIO servers in the deployment
simultaneously. MinIO operations are atomic and strictly consistent and
as such the restart process is non-disruptive to applications.
MinIO strongly recommends only performing simultaneous upgrade-and-restart procedures. Do not perform "rolling" (e.g one node at a time) upgrade procedures.
Examples
Use mc admin update to update each minio server process in the
MinIO deployment:
mc admin update ALIASReplace ALIAS <mc admin update ALIAS> with the alias <mc alias> of
the MinIO deployment.
Syntax
mc admin update
has the following syntax:
mc admin update ALIAS [MIRROR_URL]mc admin update
supports the following arguments:
ALIAS
The alias <mc alias> of the MinIO deployment to
update.
If the specified ALIAS corresponds to a distributed
MinIO deployment, mc admin update updates all MinIO servers
in the deployment at the same time.
Use mc alias list to
review the configured aliases and their corresponding MinIO deployment
endpoints.
MIRROR_URL
The mirror URL of the minio server binary to use for
updating MinIO servers in the ~mc admin update ALIAS deployment.
