Editor's Notes
- #6 To deploy app, developer has to specify which cloud foundry the CF CLI should talk to. The push command uploads each file and subdirectory in current directory to CF. CF then tries to detect the programming language and framework of the application and then it builds executable app from uploaded files. This means, CF installs the required runtime, libraries etc.
- #8 Use declarative formats for setup automation, to minimize time and cost for new developers joining the project; Have a clean contract with the underlying operating system, offering maximum portability between execution environments; Are suitable for deployment on modern cloud platforms, obviating the need for servers and systems administration; Minimize divergence between development and production, enabling continuous deployment for maximum agility; And can scale up without significant changes to tooling, architecture, or development practices.
- #9 CCDB is Cloud Controller DB, which stores service creds etc. Cloud controller provides REST API for clients to communicate with system. Service Broker API is used to communicate with 3rd party services – hosted in CF, or completely outside CF.
