3.6 Set Up etcd as Data Store

Create a data store for MicroTx to store the transaction logs. You can use either etcd or Oracle Database as the data store.

Skip this section if you want to set up Oracle Database as data store. See Set Up Oracle Database as Data Store.

Before installing MicroTx, you must install and configure a data store. Ensure that you set up the required networking rules to allow communication between the transaction coordinator and the data store.

Ensure that you have the required permissions to create tables in the database. When you install MicroTx, the service creates the required tables in the database. So MicroTx requires certain details about the database.

Topics:

• Generate RSA Certificates for etcd
  You must provide etcd credentials and etcd endpoints in the YAML file for the transaction coordinator. MicroTx uses this information to establish a connection to the database after the service is installed.
• Create a Kubernetes Secret for etcd
  You must provide etcd credentials and etcd endpoints in the values.yaml file. MicroTx uses this information to establish a connection to etcd after the service is installed.
