The document discusses continuous delivery using Jenkins, Docker, and Spring Boot. It describes continuous delivery as getting changes into production quickly and safely. It then explains how continuous integration, automated testing, and using a continuous delivery pipeline with Docker can help achieve this. Key points are that Docker allows applications to be packaged and run the same way anywhere, and treating servers as "cattle not pets" allows easy replacement and consistency across environments.

The ability to get changes-features, configuration changes, bug
fixes, experiments - into production or into the hands of users
safely and quickly in a sustainable way

30. issues?
● Each server has to be configured
● Different environment in staging and production
● Different Java version for different applications
● Applications using the same ports
● Versioning

36. treat your servers like cattle,
not pets

40. Dockerfile:
FROM frolvlad/alpine-oraclejdk8:slim
ADD build/libs/exchange-0.0.1-SNAPSHOT.jar app.jar
ENTRYPOINT ["java","-jar","app.jar"]

41. Dockerfile:
FROM frolvlad/alpine-oraclejdk8:slim
ADD build/libs/exchange-0.0.1-SNAPSHOT.jar app.jar
ENTRYPOINT ["java","-jar","app.jar"]
docker build -t <image_name> .

42. $ docker run --name <container_name> <image_name>

43. $ docker run --name <container_name> <image_name>

44. Docker registry
● registry for docker
images

45. Docker image name
<registry_address>/<image_name>

46. Docker image name
<registry_address>/<image_name>
docker push <image_name>

47. Docker image name
<registry_address>/<image_name>
docker push <image_name>
docker pull <image_name>

48. Port Mapping
$ docker run -p 8080:8080 --name <container_name>
<image_name>

49. External Docker Host
$ docker run -p 8080:8080 --name <container_name>
<image_name>
$ docker run -H 192.168.0.15:2375 -p 8080:8080 --name
<container_name> <image_name>

50. Example
$ docker run -H 192.168.0.15:2375 -p 8080:8080 -d
--name exchange-rate 192.168.0.20/exchange-rate:15
