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.
After running the command, a prompt displays to confirm the update.
Type y
and [ENTER]
to confirm and proceed with the update.
You may need to use sudo
if your user does not have write permissions for the path where mc
is installed.
Use mc admin
on MinIO Deployments Only
MinIO does not support using mc admin
commands with other
S3-compatible services, regardless of their claimed compatibility with MinIO
deployments.
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” (that is, 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 ALIAS
Replace ALIAS
with the alias
of the MinIO deployment.
After running the command, answer yes to the prompt to confirm and process the update.
