Docker Introduction
Docker Concept VM vs Container VM - Base on OS Container - Base on Application (Linux Kernel: Namespace and Cgroup) Client to Server Docker daemon - containerd, docker-containerd-shim, docker-runc Docker client - cli command docker cli -> docker daemon -> containerd -> runc -> namespace & cgroup Image Snapshots Container Read-Only processes on image Hub / Registry Store images References Docker —— 從入門到實踐 docker docs Docker commands Dockerfile ARG dist="/tmp/password" ARG projectDir="/password" FROM golang:1.16-alpine3.14 AS builder RUN apk add build-base upx ARG dist ARG projectDir WORKDIR ${projectDir} COPY . .
