Run docker-compose without access to environment variables - windows

Is it possible to run a docker-compose.yml file without having access to the environment variables (on windows)? I have docker desktop installed successfully. Below is the docker-compose.yml.

in redis master-slave-sentinel configuration and Spring boot application, RedisConnectionException occured

I configured redis master-slave-sentinel environment using docker-compose.
and I completed it and tested it.
but, in my spring boot application, I wrote a redis sentinel config code.
below spring config class.
#Configuration
#EnableRedisRepositories
public class RedisConfig {
#Bean
public RedisConnectionFactory redisConnectionFactory(){
RedisSentinelConfiguration redisSentinelConfiguration = new RedisSentinelConfiguration()
.master("redis-master")
.sentinel("localhost",26379)
.sentinel("localhost",26380)
.sentinel("localhost",26381);
LettuceConnectionFactory lettuceConnectionFactory = new LettuceConnectionFactory(redisSentinelConfiguration);
return lettuceConnectionFactory;
}
}
and then I did run application, then problem occured.
enter image description here
I think there are some docker-compose network configs....
I want to know why it was...
If you guys know, .. please let me know about it.
↓ redis master-slave-sentinel config docker-compose.yml code.

Everything works well under Linux but if I try to run the same file under Mac I get:
CO_ES_01 | "stacktrace": ["java.net.UnknownHostException: CO_ES_02",
Do I need specific configuration under Mac for it to work?

Why does the connect-datagen container of my confluent kafka docker-compose disconnect after a couple of minutes?

I am trying to run a bare minimum confluent community example on docker for windows (toolbox) using the example given here:
https://docs.confluent.io/current/quickstart/cos-docker-quickstart.html
but seems like all components gets started only connect is failing of them does not work,
And this is my docker-compose.yml

Can you help me?
I had same problem and found solution.
We should focus on the docker container status exited 137. this mean is out-of-memory for container. therefore you must allocate minimally at 6 GB for Docker memory.
You can also check the documentation at Prerequisites:
https://docs.confluent.io/platform/current/quickstart/cos-docker-quickstart.html

Failed to establish a new connection, Docker-Compose Django + Haystack + Mysql + ElasticSearch

When I enter on the url http://0.0.0.0:9200/ is working.
I am getting the following error when I want to save or retrieve data:
ConnectionError(<urllib3.connection.HTTPConnection object at
0x7f234afdacc0>: Failed to establish a new connection: [Errno 111]
Connection refused) caused by:

I tried to create e network between web and elastic search, same result.
When I call http://0.0.0.0:9200/ I get a response from server with a JSON.
My Haystack config in settings.py
HAYSTACK_CONNECTIONS = {
'default': {
'ENGINE':'haystack.backends.elasticsearch_backend.ElasticsearchSearchEngine',
'URL': '0.0.0.0:9200/',
'INDEX_NAME': 'haystack'
}
}
HAYSTACK_SIGNAL_PROCESSOR = 'haystack.signals.RealtimeSignalProcessor'
Some content so I can post this question, Is not only code.
You should use elasticsearch instead of 0.0.0.0:
HAYSTACK_CONNECTIONS = {
'default': {
'ENGINE':'haystack.backends.elasticsearch_backend.ElasticsearchSearchEngine',
>>> 'URL': 'elasticsearch:9200',
'INDEX_NAME': 'haystack'
}
}
