Java utility to automate user creation and deletion in Oracle Cloud infrastructure

• You should have Maven and Git installed

• For admin privileged user which can execute user management operations to run the utility

  • keep the private key (.PEM format) ready - private key for admin privileged user which can execute user management operations
  • keep config file ready - this should contain info for admin privileged user which can execute user management operations

    • make sure you have the DEFAULT profile specified

        [DEFAULT]
        user=ocid1.user.oc1..aaaaaaaa7grmsqmsx27zuhcqesvb5dvhrwppxtpoxhlvfxvlukuwdypzeg2q
        fingerprint=42:82:5f:44:ca:a1:2e:58:d2:63:6a:af:52:d5:3d:42
        key_file=/test/private_key.pem
        pass_phrase=4242
        tenancy=ocid1.tenancy.oc1..aaaaaaaapsj3hr6pl4abnz52jm3wkgf2gfxymbeofzswhcp5jdem3fhjmkeq
        region=us-phoenix-1
      

  • make sure that you enter the full path for your private key in the key_file attribute in your config file

• for the end user, keep the following ready

  • public key (PEM format as per OCI doc) - this needs to be specified in the properties file for the user creation process
  • private key (PEM format as per OCI doc) - this needs to be provided to end users

• git clone https://github.com/abhirockzz/oci-user-management-util

• Seed OCI SDK to your local Maven repo

  • chmod +x seed-oci-sdk-to-maven.sh
  • run the script ./seed-oci-sdk-to-maven.sh
  • it pulls down the OCI SDK from https://github.com/oracle/oci-java-sdk/releases and seeds it to local Maven using mvn install

• create a properties file with the required info for creation or deletion (you can use util.properties as a template)

    #common parameters
    
    config_file_path=/test/oci/config
    group_ocid=ocid1.group.oc1..aaaaaaaa46umbo4kgln6jc3q2mgx5o76hycj2g55hjykwnaxz4l6epy72tnq
    username_prefix=workshop
    
    #creation
    
    user_public_key_path=/test/oci_api_key_public.pem
    start_user_sequence=101
    num_of_users=2
  

Both user and deletion utilities lists down the affected users (to be created or deleted) and prompts you for confirmation before triggering the actual process (just to be safe)

• creates user
• generates one time (temporary) password (just like UI) - this needs to be copied and saved for distributing it to users
• adds to a group
• uploads public key

• cd oci-user-management-util/create-users-util
• mvn clean install - check target directory for presence of create-users-1.0.jar
• enter configuration in util.properties
• java -jar target/create-users-1.0.jar ../util.properties (you can point to a different properties file as well)

• removes user from group
• deletes the user

• cd oci-user-management-util/delete-users-util
• mvn clean install - check target directory for presence of delete-users-1.0.jar
• enter configuration in util.properties
• java -jar target/delete-users-1.0.jar ../util.properties (you can point to a different properties file as well)
