32. 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

not pets

42. Dockerfile:
FROM frolvlad/alpine­oraclejdk8:slim
ADD build/libs/vox­0.0.1­SNAPSHOT.jar app.jar
ENTRYPOINT ["java","­jar","app.jar"]

43. FROM frolvlad/alpine­oraclejdk8:slim
ADD build/libs/vox­0.0.1­SNAPSHOT.jar app.jar
ENTRYPOINT ["java","­jar","app.jar"]
docker build ­t <image_name> .
Dockerfile:

44. $ docker run ­­name <container_name> <image_name>

45. $ docker run ­­name <container_name> <image_name>

46. Docker registry
● registry for docker
images

47. <registry_address>/<image_name>

48. <registry_address>/<image_name>
docker push <image_name>

49. <registry_address>/<image_name>
docker push <image_name>
docker pull <image_name>

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

51. 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>

52. Example
$ docker run ­H 192.168.0.15:2375 ­p 8080:8080 ­d
­­name exchange­rate 192.168.0.20/exchange­rate:15
