Sebuah container interaktif

Sebuah bug lain muncul di pipeline ingestion data; namun kali ini, Anda mendapat beberapa petunjuk tentang lokasi masalahnya. Rekan Anda memberi tahu bahwa aplikasi tidak dapat berjalan di dalam container Ubuntu-nya. Untuk men-debug masalah tersebut, Anda ingin memulai sebuah container Ubuntu dan mencoba menjalankan aplikasinya sendiri untuk mencari tahu apa yang salah.

Pilih kombinasi perintah yang tepat untuk:

Menjalankan container ubuntu dan mendapatkan shell interaktif di dalam container.
Menutup container untuk kembali ke host setelah Anda mendapatkan shell interaktif di container dan menemukan masalah pada pipeline.

Anda dapat menggunakan shell untuk mencoba perintah-perintah yang mungkin.

Once you are able to manage images and containers, it's time to know how to share images with colleagues or your entire company and to understand how to create your own. Now, you'll build your own images using Dockerfiles. Dockerfiles are text files that include everything needed for Docker to build an image. You'll learn how to create images and will get an introduction to all the essential Dockerfile instructions like FROM, RUN, COPY, and more. By the end of this chapter, you'll have insight into how Docker makes images and be able to create optimized Docker images from scratch.

In this final chapter, you’ll focus on making your Dockerfiles configurable and secure. You'll learn how to make your Dockerfiles configurable using the ARG and ENV instructions. You’ll see why changing the user in your images makes them more secure and how to use the USER Dockerfile instruction to do so. To wrap things up, you’ll learn about some essential security best practices when creating Docker Images.
