MinIO Multi-user Quickstart Guide ![Slack](https://slack.min.io/slack?type=svg)
MinIO supports multiple long term users in addition to default user created during server startup. New users can be added after server starts up, and server can be configured to deny or allow access to buckets and resources to each of these users. This document explains how to add/remove users and modify their access rights.
Get started
In this document we will explain in detail on how to configure multiple users.
1. Prerequisites
- Install mc - MinIO Client Quickstart Guide
- Install MinIO - MinIO Quickstart Guide
- Configure etcd (optional needed only in gateway or federation mode) - Etcd V3 Quickstart Guide
2. Create a new user with canned policy
Use mc admin policy
to create canned policies. Server provides a default set of canned policies namely writeonly
, readonly
and readwrite
(these policies apply to all resources on the server). These can be overridden by custom policies using mc admin policy
command.
Create new canned policy file getonly.json
. This policy enables users to download all objects under my-bucketname
.
cat > getonly.json << EOF
{
"Version": "2012-10-17",
"Statement": [
{
"Action": [
"s3:GetObject"
],
"Effect": "Allow",
"Resource": [
"arn:aws:s3:::my-bucketname/*"
],
"Sid": ""
}
]
}
EOF
Create new canned policy by name getonly
using getonly.json
policy file.
mc admin policy add myminio getonly getonly.json
Create a new user newuser
on MinIO use mc admin user
.
mc admin user add myminio newuser newuser123
Once the user is successfully created you can now apply the getonly
policy for this user.
mc admin policy set myminio getonly user=newuser
3. Create a new group
mc admin group add myminio newgroup newuser
Once the group is successfully created you can now apply the getonly
policy for this group.
mc admin policy set myminio getonly group=newgroup
4. Disable user
Disable user newuser
.
mc admin user disable myminio newuser
Disable group newgroup
.
mc admin group disable myminio newgroup
5. Remove user
Remove the user newuser
.
mc admin user remove myminio newuser
Remove the user newuser
from a group.
mc admin group remove myminio newgroup newuser
Remove the group newgroup
.
mc admin group remove myminio newgroup
6. Change user or group policy
Change the policy for user newuser
to putonly
canned policy.
mc admin policy set myminio putonly user=newuser
Change the policy for group newgroup
to putonly
canned policy.
mc admin policy set myminio putonly group=newgroup
7. List all users or groups
List all enabled and disabled users.
mc admin user list myminio
List all enabled or disabled groups.
mc admin group list myminio
8. Configure mc
mc config host add myminio-newuser http://localhost:9000 newuser newuser123 --api s3v4
mc cat myminio-newuser/my-bucketname/my-objectname
