Connection error for cassandra and influxdb when using docker-compose - docker-compose

I am using docker-compose for influxdb and Cassandra for my application but when I am trying to run application locally on my mac system I am getting below error - I am new for both so not sure where to make the changes for IPs for both docker images.
for Cassandra -
Connection error: ('Unable to connect to any servers', {'127.0.0.1': error(111, "Tried connecting to [('127.0.0.1', 9042)]. Last error: Connection refused"), '::1': error(99, "Tried connecting to [('::1', 9042, 0, 0)]. Last error: Cannot assign requested address")})
For Influxdb - when trying to create a user programmatically
curl: (6) Could not resolve host: influxdb

CraftCMS with Redis: Failed to open redis DB connection (tcp://:, database=): 0 - Failed to parse address ":"

I have yii2 and yii2-redis installed on a CraftCMS project, but when I fire up the project, I get an error message that reads:
Database Exception – yii\db\Exception
Failed to open redis DB connection (tcp://:, database=): 0 - Failed to parse address ":"
Error Info: Failed to parse address ":"
I'm not quite sure what to do with this error. In my .env file, I put in:
REDIS_HOST=localhost
REDIS_PORT=3306
REDIS_PASSWORD=
REDIS_KEY_PREFIX=craft
But that only yielded a different error:
Database Exception – yii\db\Exception
Failed to open redis DB connection (tcp://:3306, database=): 0 - php_network_getaddresses:
getaddrinfo failed: nodename nor servname provided, or not known
Error Info: php_network_getaddresses: getaddrinfo failed: nodename nor servname provided, or not known
Help?
Additional context: I didn't set up the build for this project, so I more or less inherited this Redis setup.
Update:
I went and dug into the config file for the Redis setup and found a misnaming between the .env variables and what was present in the .env file. Now I'm getting a completely different error:
"Received illegal data from redis: Redis command was: SELECT 0"

Please check that your configuration matches the environment variables you use.

Turns out I'd deleted the Redis database (don't remember how or when), so creating a new one (with the correct .env variables set) fixed the problem immediately.
Whew.

GCloud SQL Proxy cannot connect, unclear errors

I am having difficulty getting the gcloud sql proxy working on my local machine. I have gone through all the steps here however I am getting the following errors. It is unclear to me what is actually going wrong. Important things to note, I am not using a service account, I am authenticating with my own account through gcloud auth login and I am following the TCP sockets steps.

The most likely reason you are receiving this error message is because you are using a First Generation instance.
