Docker components
• Images
• Containers
• Daemon
• Registries
• Clients
@xcoulon#Devoxx #Docker #Eclipse
Docker Images
• "build" components
• read-only templates
• combination of layers
@xcoulon#Devoxx #Docker #Eclipse
Docker Containers
• "run" components
• based on Images
• contain application and dependencies but share same kernel
• can be started, stopped, paused, deleted
• containers are immutable and disposable
@xcoulon#Devoxx #Docker #Eclipse
Docker Daemon
• runs natively on Linux
• inside a VM on Windows and Mac OS X
@xcoulon#Devoxx #Docker #Eclipse
Docker Registries
• "distribution" components
• public instances (https://hub.docker.com)
• private instances
@xcoulon#Devoxx #Docker #Eclipse
Benefits of Docker
• No need for an hypervisor for each container
• many containers per VM
• less memory/CPU resources
• Density, infrastructure utilization
@xcoulon#Devoxx #Docker #Eclipse
Benefits of Docker
• Package the full stack in a container:
• OS,
• JVM,
• App server
• Application with its configuration
• Portable across environments
• Developer machine
• CI / Staging / Production environments
• No more "but it works on my machine" argument
