1.构建
运行以下命令构建，只用运行一次镜像构建，如果修改了 dockerfile 才重新再运行：
docker_build.sh:
1
2
3
4
5
6
7
| #!/bin/bash
set -e # 任何一步失败立即退出，不再误报"构建完成"
IMAGE_NAME=rk3288-android10-env
IMAGE_TAG=latest
docker build -t ${IMAGE_NAME}:${IMAGE_TAG} -f Dockerfile .
echo "构建完成: ${IMAGE_NAME}:${IMAGE_TAG}"
|
Dockerfile:
可自行修改添加编译依赖

| #!/bin/bash
# 用法: ./docker_run.sh -> 以 htx 进入，exit 后自动停止容器
# ./docker_run.sh root -> 以 root 进入，exit 后自动停止容器
CONTAINER_NAME=rk3288-build
IMAGE=rk3288-android10-env:latest

if ! docker ps -a --format '{{.Names}}' | grep -q "^${CONTAINER_NAME}$"; then

docker create -it \

# 进入容器
if [ "$1" = "root" ]; then

else

docker stop ${CONTAINER_NAME} > /dev/null

3.保存导出当前 docker 镜像
docker_save.sh:

| #!/bin/bash
CONTAINER_NAME=rk3288-build
IMAGE=rk3288-android10-env:latest
OUT_FILE=rk3288-android10-env_$(date +%Y%m%d).tar.gz
# 关键：先 commit，容器里后来 apt 装的包才会一起保存
if docker ps -a --format '{{.Names}}' | grep -q "^${CONTAINER_NAME}$"; then
echo "提交容器当前状态 -> ${IMAGE}"
docker commit ${CONTAINER_NAME} ${IMAGE}
fi
echo "导出镜像 -> ${OUT_FILE}"
docker save ${IMAGE} | gzip > "${OUT_FILE}"
echo "完成，大小: $(du -h "${OUT_FILE}" | cut -f1)"
echo "目标机器恢复: docker load -i ${OUT_FILE}"
