A connection to a Redis database is expected to run the application successfully. You need to download and run Redis DB on your local machine with default values localhost 6379.

You can also run the application via Docker.

docker-compose up --build -d

However, you need either to run it with Spring Cloud Config application or override property value from redis.host = localhost to redis.host = redis. Where value "redis" will be treated as a DB service address and used for connection between docker images.

Operations on Redis DB

Use Redis CLI or attach to Redis docker image in order to manually operate on DB.

docker exec -it mockedservices_redis-server redis-cli

Attach to redis server image and open a redis client.

Useful redis-cli commands:

KEYS *

Show all keys in the db.

TYPE key

Show key type.

LRANGE key start stop

Display elements from the list.

LLEN key

Display list length.

SMEMBERS key

Display elements from hashSet. Logs can be found in lists with names logstash_yyyy-mm-dd.

Deployment and building with docker and jenkins

For creating docker context (feature available from docker version 19.03):

docker context create DEV
--description "context for DEV environment"
--docker "host=ssh://jenkins@s5000xvn:22"

docker context create PROD
--description "connection to PROD environment"
--docker "host=ssh://jenkins@server361209.nazwa.pl:22"

docker context create PROD
--description "context for PROD environment"
--docker "host=ssh://jenkins@server361209:22"

docker-compose up -d --build

Builds and launches Redis service and the application. Performs unit testing on the code and run the application.

docker-compose --context DEV up --build -d

The same as above, but the application will be deployed on the server defined via docker context as DEV.

docker-compose --context PROD up --build -d

The same as above, but the application will be deployed on the server defined via docker context as PROD.

The application can be started on a local machine without environment support. However, for application supervising and updating configuration on deployment spring cloud applications should be deployed before. In order:

Spring Cloud Eureka
Spring Cloud Configuration
MockedServices Once a docker image repository will be availabe, the proper deployment order should be under control by docker-compose script which should check if the applications are present and if not deploy stable images of Spring Cloud applications from docker image repo.
