OCI Utilities

Instances using Oracle Linux platform images include a set of utilities (oci-utils) that allow the instance to access information about infrastructure resources. These utilities consist of a service component and command line tools that help automatically discover or provision resources.

Installing the OCI Utilities

Instances launched with Oracle Linux 7 or later automatically include the Oracle Cloud Infrastructure (OCI) utilities (oci-utils) package installed. The utilities aren't available on other distributions.

To use the utilities, you must ensure the following prerequisites are met:

  • Ensure that the oci_included repository is enabled. This repository is enabled by default in Oracle Linux platform images. This repository contains all package dependencies, including the required OCI SDK and Python packages. All required packages are installed with the oci-utils package.
  • Ensure that the OCI utilities have sufficient permissions to access Oracle Cloud Infrastructure by using one of the following methods:
    • Create the SDK configuration file for the host. For more information, see SDK and CLI Configuration File.
      Note

      You might need to install the CLI for your environment before running the oci setup config command to create the SDK configuration file. For more information, see Installing the CLI.
    • Use instance principals by adding the instance to a dynamic group that was granted access to Oracle Cloud Infrastructure services. For more information, see Managing Dynamic Groups.
    • Configure oci-utils to allow root to use a non-privileged user's Oracle Cloud Infrastructure configuration files. For more information, see the configuration file located in the /etc/oci-utils.conf.d directory of the instance.
  • Choose the method to access the OCI utilities, and perform any setup procedures for that method, as needed:

For a video on how to install and set up the OCI utilities, see Enabling OCI Utilities in Oracle Linux on Oracle Cloud Infrastructure Instances in the Oracle Linux Training Station.

Updating the OCI Utilities

To update to the latest version of oci-utils:

sudo yum update oci-utils

Using the ocid Daemon

The ocid daemon is the service component of the oci-utils. It monitors for changes in the VNIC and iSCSI configuration of the instance and attempts to automatically attach or detach devices as they appear or disappear - for example, when they are created or deleted using the Oracle Cloud Infrastructure Console, CLI, or the API.

To start the ocid daemon using systemd and set the ocid service to start automatically during system boot:

sudo systemctl enable --now ocid.service

To confirm that the service is active (running):

sudo service ocid status

For example:

$ sudo service ocid status
Redirecting to /bin/systemctl status ocid.service

oci-compartmentid

Use the oci-compartmentid utility to display the OCID of the compartment where the instance is running.

Usage

oci-compartmentid [-h | --help]

To view the compartment OCID of the instance:

sudo oci-compartmentid

For example:

$ sudo oci-compartmentid
ocid1.compartment1.oc1..OCID

For information about the oci-compartmentid utility option, see Common OCI Utility Options.

oci-growfs

If you expand the boot volume of an Oracle Cloud Infrastructure (OCI) Linux-based instance, you can then use the oci-growfs utility to expand the root partition of the instance. This lets you fully use the newly expanded boot volume.

Note

Only XFS and ext4 file systems are supported.

By default, a Linux-based instance doesn't automatically use the entire boot volume if the boot volume is larger than or equal to 50 GB. If the boot volume attached to the instance is less than 50 GB, no changes are made to the system when using the oci-growfs utility.

Usage

/usr/libexec/oci-growfs [-y] [-n] [-h | --help]

Expanding the Root Partition of an Instance

To expand the root partition of the instance:

  1. Use the lsblk command to confirm the OS has identified the new size of the boot volume.

    For example:

    lsblk
    NAME               MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
    sda                  8:0    0  100G  0 disk
    ├─sda1               8:1    0  100M  0 part /boot/efi
    ├─sda2               8:2    0    1G  0 part /boot
    └─sda3               8:3    0 98.9G  0 part
      ├─ocivolume-root 252:0    0 88.9G  0 lvm  /
      └─ocivolume-oled 252:1    0   10G  0 lvm  /var/oled
    sdb                  8:16   0   70G  0 disk
    

    If the disk volume isn’t the expected size, run the commands to rescan the boot volume. See Rescanning the Disk for Volumes Attached to Linux-Based Instances.

  2. Run the oci-growfs utility with the y option to answer "yes" to all prompts.

    sudo /usr/libexec/oci-growfs -y

    For example:

    $ sudo /usr/libexec/oci-growfs -y

For example, to view only the state of the compute instance:

$ sudo oci-metadata --get state
Instance details:
Instance state: Running

Option Details

The following table provides detailed information about options specific to this utility or subcommand. For information about the common options used across OCI utilities, see Common OCI Utility Options.

oci-metadata Option Details

Option

Description

-g key | --get key

Retrieve data only for the specified key. The metadata keys for an instance can be defined by Compute or you can create custom keys. For more information, see Metadata Keys.

--export

Used with the -g or --get option, display a shell command to export the key as an environment variable.

--trim

Used with the -g or --get option, trim the key path to the last component to make the output more concise. For example: instance/metadata/ssh_authorized_keys to ssh_authorized_keys. If the key matches multiple keys, only the first matching key is displayed.

--value-only

Used with the -g or --get option, display only the values matching the get key.

-u key_value

Update the value for the specific key (or keys). For key_value, specify a string, a JSON value, or a pointer to a file with JSON content in the following format: key=file:/path/to/file

-i | --instance-id OCID

Get or update the metadata of the instance with the specific OCID. By default, oci-metadata works with the metadata from the instance that you logged in to.

oci-network-config

The oci-network-config utility lets you configure network interfaces for the instance. This utility must be run as root.

The oci-network-config utility shows the current virtual network interface cards (VNICs) provisioned in Oracle Cloud Infrastructure (OCI) and configured for this instance. When a secondary VNIC is provisioned in OCI, it must be explicitly configured on the instance using the oci-network-config utility.

The network interfaces that are being configured can be placed inside separate network namespaces. This separation is necessary when VNICs are in subnets (different VCNs) with overlapping address blocks and the network applications aren't bound directly to the interfaces. Network namespaces require applications to be launched in the namespaces explicitly (with the ip netns exec ns command) to establish association with the interface. When namespaces aren't used, policy-based routing is configured to provide a default route to the secondary VNIC´s virtual router (default gateway) when the VNIC´s address is the source address.

Bare metal secondary VNICs are configured using VLANs (where there is no corresponding physical interface). These VNICs appear as two additional interfaces when showing IP links, with names in MACVLAN_FORMAT for the MAC VLAN and VLAN_FORMAT for the IP VLAN.

Usage

oci-notify

The oci-notify utility sends a message to a Notifications service topic. This utility must be run as root.

A message is composed of a message header (title) and file. The Notifications service configuration for the topic determines where and how the messages are delivered. Topics are configured using the Oracle Cloud Infrastructure (OCI) Console, API, or CLI.

For more information about the Notifications service, including how to create topics, see Notifications Overview.

Usage

oci-notify [subcommand] [-h | --help]

Subcommands

The oci-notify utility has the following subcommands.

Publishing a Message to a Topic

For information about the oci-notify utility option, see Common OCI Utility Options.

Configuring a Notifications Service Topic on an Instance

Use the oci-notify config subcommand to write the Notifications service topic OCID to the oci.conf file. After configured, you can publish messages to this configured topic.

By default, the path to the configuration file is /etc/oci-utils/oci.conf. You can override the configuration file path by using the OCI_CONFIG_DIR environment variable.

Usage

oci-notify config notifications_topic_OCID [-h | --help]

To write the OCID of a configured Notifications service topic to the oci.conf file, use the oci-notify config subcommand, and specify the Notifications service topic OCID.

For example:

$ sudo oci-notify config ocid1.onstopic.oc1..OCID

For information about the oci-notify-config utility option, see Common OCI Utility Options.

Publishing a Message to a Topic

With the oci-notify message subcommand, you can publish the contents of a file or a text string with the specified title to the configured topic.

Note: When the message is published, the oci-notify utility prepends the instance name to the subject of the message. For example: instance_name:log messages

Usage

oci-notify message [-t | --title 'message_title'] [-f | --file message_file] [-h | --help]

To send the contents of the /var/log/messages file with the title 'logging messages' to the configured topic, use the --title and --file options with the oci-notify-message subcommand.

For example:

$ sudo oci-notify message --title 'logging messages' --file /var/log/messages

To send a text string to the configured topic, enter a line of text in single quotation marks for the value of the --file option.

For example:

$ sudo oci-notify message --title 'sending a text' --file 'Today is a beautiful day'

Option Details

The following table provides detailed information about options specific to this utility or subcommand. For information about the common options used across OCI utilities, see Common OCI Utility Options.

oci-notify-message Option Details

Option

Description

-t | --title message_title

Specify the title to be used in the message header (for example, 'log messages' if you're sending log files). The message_title must be enclosed in either single or double quotation marks. Message headers are truncated to 128 characters.

-f | --file message_file

Specify the full or relative directory path, HTTP, or FTP URL of the message file or the text string to be sent. Larger files are split into 64-KB chunks and are sent as separate messages. The number of chunks is limited to 10.

If the specified message_file isn't recognized as a URL or the directory path doesn't exist, the text entered for message_file is sent as a text string. Text strings are limited to 128 characters.

oci-public-ip

Use the oci-public-ip utility to display the public IP address of the current compute instance, in either human-readable or JSON format.

The oci-public-ip utility uses the Oracle Cloud Infrastructure (OCI) SDK to discover the IP address (see Software Development Kits and Command Line Interface). If the IP address can't be obtained by this method, the oci-public-ip utility then tries the Session Traversal Utilities for NAT (STUN) protocol as a last resort to discover the IP address. For more information about STUN, see the STUN Wikepedia article.

Usage

oci-public-ip [-h | --human-readable] [-j | --json] [-g | --get] [-a | --all] [-s | --sourceip source_IP] [-S | --stun-server STUN_server] [-L | --list-servers] [--instance-id OCID] [--help]

Displaying the IP Address of the Current Instance

Run the oci-public-ip command with no options to return the IP address of the current instance:

sudo oci-public-ip

For example:

$ sudo oci-public-ip
Public IP address: 203.0.113.2

Displaying the IP Address of Another Instance

To view the public IP address of another instance other than the current instance, use the oci-public-ip utility with the --instance-id option.

Note

This option requires the OCI SDK for Python to be installed and configured. For more information, see Software Development Kits and Command Line Interface.
sudo oci-public-ip --instance-id OCID

For example:

$ sudo oci-public-ip --instance-id ocid1.instance.oc1.phx.OCID
Public IP address: 203.0.113.2

Viewing a List of STUN Servers

To display a list of STUN servers, use the oci-public-ip utility with the --list-servers option:

sudo oci-public-ip --list-servers

For example:

$ sudo oci-public-ip --list-servers
stun.stunprotocol.org
stun.counterpath.net
stun.voxgratia.org
stun.callwithus.com
stun.ekiga.net
stun.ideasip.com
stun.voipbuster.com
stun.voiparound.com
stun.voipstunt.com

-L | --list-servers

Prints a list of known STUN servers and exits.

-s | --sourceip source_IP

Specifies the source IP address to use.

-S | --stun-server STUN_server

Specifies the STUN server to use.

oci-volume-data

Use the oci-volume-data utility to view data about a specific iSCSI volume attached to an Oracle Linux-based compute instance.

The oci-volume-data utility requires the -k (key) option to display data for a specific iSCSI volume. Key option values can be the display name, OCID, or iqn (iSCSI Qualified Name) of the volume.

Usage

oci-volume-data [-h | --help] [-k KEY | --key KEY] [-p | --par {name, iqn, ocid, portal, chap, attachestate, avdomain, compartment, attached, size, state}] [-v | --value-only]

Viewing All Data About an Attached iSCSI Volume

To view all data about an iSCSI volume attached to the compute instance:

sudo oci-volume-data -k OCID

For example:

$ sudo oci-volume-data -k OCID
             display name: name=oci1-iscsi-volume-1
                     ocid: ocid1.volume.oc1.OCID
                      iqn: iqn.2122-45.com.oracleiaas:IQN
                portal ip: 123.245.6.7
              portal port: 1234
                chap user: None
            chap password: None
      availability domain: DSdu:US-EAST-DOMAIN
              compartment: comparment1
           compartment id: ocid1.compartment.OCID
              attached to: oci-utils-instance
         attachment state: --
                     size: 70GB
                    state: AVAILABLE

Viewing Specific Data About an Attached iSCSI Volume

Optionally use the -k, -p, and -v (value-only) options with the oci-volume-data utility to narrow down what you want displayed for the iSCSI volume:

oci-volume-data -k OCID -p size -v

For example, to display only the size of an iSCSI volume, in this case, 70 GB:

$ oci-volume-data -k ocid1.volume.OCID -p size -v
70GB

For more information about the supported option values (such as size, state, compartment, and so on), see the man page for oci-volume-data. For information about accessing OCI utility man pages, see Common OCI Utility Options.
