 ## Overview of Running Oracle RAC in Containers
 
-Oracle Real Application Clusters (Oracle RAC) is an option for the award-winning Oracle Database Enterprise Edition. Oracle RAC is a cluster database with a shared cache architecture that overcomes the limitations of traditional shared-nothing and shared-disk approaches to provide highly scalable and available database solutions for all business applications. Oracle RAC uses Oracle Clusterware as a portable cluster software that allows clustering of independent servers so that they cooperate as a single system, and Oracle Automatic Storage Management (Oracle ASM) to provide simplified storage management that is consistent across all servers and storage platforms. Oracle Clusterware and Oracle ASM are part of the Oracle Grid Infrastructure, which bundles both solutions in an easy-to-deploy software package. For more information on Oracle RAC Database 21c, refer to the [Oracle Database documentation](http://docs.oracle.com/en/database/).

 Before you start the installation, you must plan your private and public network.

You can create a `network bridge` on every container host so containers running within that host can communicate with each other. For example:  create `rac_pub1_nw` for the public network (`10.0.20.0/24`) and `rac_priv1_nw` (`192.168.17.0/24`) for a private network. You can use any network subnet for testing. In this document we define the public network on `10.0.20.0/24` and the private network on `192.168.17.0/24`.

  ```
 
 ## Password Management 
 - Specify the secret volume for resetting the grid, oracle, and database user password during node creation or node addition. The volume can be a shared volume among all the containers. For example:
 
-   ```bash
-   mkdir /opt/.secrets/
-   ```
+```bash
+mkdir /opt/.secrets/
+```
 - Generate a password file - Edit the `/opt/.secrets/pwdfile.txt` and seed the password for the grid, oracle, and database users. For this deployment scenario, it will be a common password for the grid, oracle, and database users. Run the command:
 
-    ```bash
-    cd /opt/.secrets
-    openssl genrsa -out key.pem
-    openssl rsa -in key.pem -out key.pub -pubout
-    openssl pkeyutl -in pwdfile.txt -out pwdfile.enc -pubin -inkey key.pub -encrypt
-    rm -rf /opt/.secrets/pwdfile.txt
-    ```
+```bash
+cd /opt/.secrets
+openssl genrsa -out key.pem
+openssl rsa -in key.pem -out key.pub -pubout
+openssl pkeyutl -in pwdfile.txt -out pwdfile.enc -pubin -inkey key.pub -encrypt
+rm -rf /opt/.secrets/pwdfile.txt
+```
 - Oracle recommends using Podman secrets inside the containers. To create Podman secrets, run the following command:
 
-    ```bash
-    podman secret create pwdsecret /opt/.secrets/pwdfile.enc
-    podman secret create keysecret /opt/.secrets/key.pem
+```bash
+podman secret create pwdsecret /opt/.secrets/pwdfile.enc
+podman secret create keysecret /opt/.secrets/key.pem

-    podman secret inspect <secret_name>
-    ```
+podman secret inspect <secret_name>
+```
 Notes:
 - In this example we use `pwdsecret` as the common password for SSH setup between containers for the oracle, grid, and Oracle RAC database users. Also, `keysecret` is used to extract secrets inside the Oracle RAC Containers.
