9. jgs Javier Gonzalez-Sanchez | CSC 309 | Winter 2023 | 9 Docker
10. jgs Javier Gonzalez-Sanchez | CSC 309 | Winter 2023 | 10 § Containers share the host operating system kernel, libraries, and binaries. § Virtual machines run its own guest operating system, § Virtual machines provide full-blown virtualization of hardware resources, including CPU, memory, storage, and networking. It is not VM
11. jgs Javier Gonzalez-Sanchez | CSC 309 | Winter 2023 | 11 Docker | Run Docker Engine
12. jgs Javier Gonzalez-Sanchez | CSC 309 | Winter 2023 | 12 Docker | Steps 2. A package that includes everything needed to run software, including the code, runtime, libraries, dependencies, and configuration files. 3. A container is a runtime instance of an image. It encapsulates the execution environment for a specific application or process, including the filesystem, environment variables, network settings, and runtime options. 1. A text file that contains instructions for building a Docker image
