Sometimes you might want to put something on a JMS queue and make it available after a certain period has passed to consumers. How can you achieve this using Oracle SOA Suite?

Docker host and bridged networking. Running library/httpd on different ports
Docker provides different networking options. When using the Docker host networking, you don't have the option to create port mappings. When using images like library/httpd:2.4, you don't have the option to update the port on which it runs; it runs by default on port 80. Suppose you want to use the host networking feature and want to run library/httpd:2.4 on different ports, how would you do this?
In this blog I'll explain 2 mechanisms by which you can expose library/httpd on different ports using host networking and how you can do the same using bridged networking. I'll describe several features of the different solutions and consequences for connectivity / host lookup options. At the end of the post I'll give some tips on how to test connectivity between containers.

Running Spring Tool Suite and other GUI applications from Docker containers
Running an application within a Docker container helps in isolating the application from the host OS. Running GUI applications like for example an IDE from a Docker container, can be challenging. I'll explain several of the issues you might encounter and how to solve them. For this I will use Spring Tool Suite as an example. The code (Dockerfile and docker-compose.yml) can also be found here. Due to (several) security concerns, this is not recommended in a production environment.
