[SOLVED] How do I set the password with bitnami/cassandra:4.1 and Docker compose?

How do I set the password with bitnami/cassandra:4.1 and Docker compose?

I have the following docker-compose file...

version: "3.8"     
services:       
  cassandra:         
    container_name: cassandra         
    image: bitnami/cassandra:4.1                
    ports:           
      - "9042:9042"         
    environment:           
      - CASSANDRA_AUTHENTICATOR=PasswordAuthenticator           
      - CASSANDRA_USER=cassandra           
      - CASSANDRA_PASSWORD=password

When I run and exec I see that password correctly...

$ echo $CASSANDRA_PASSWORD
password

But when I try to connect I need to use cassandra/cassandra. What am I missing how do I change the password?

I also tried this which causes it to not authenticate at all and this also worked as expected...

 - CASSANDRA_AUTHENTICATOR=AllowAllAuthenticator
 - CASSANDRA_AUTHORIZER=AllowAllAuthorizer

So I know that at least some cassandra variables are working. So I can switch off and on the password check I just can't change the password used.

Solution

You missed this env.

CASSANDRA_PASSWORD_SEEDER: Password seeder will change the Apache Cassandra default credentials at initialization. In clusters, only one node should be marked as password seeder. Default: no

So, this your docker-compose file should be:

version: "3.8"         
services:           
  cassandra:             
    container_name: cassandra             
    image: bitnami/cassandra:4.1                    
    ports:               
      - "9042:9042"             
    environment:               
      - CASSANDRA_AUTHENTICATOR=PasswordAuthenticator               
      - CASSANDRA_USER=cassandra      
      - CASSANDRA_PASSWORD_SEEDER=yes         
      - CASSANDRA_PASSWORD=password
