下载相应的版本的deb包，我的系统是ubuntu20.04，因此选择focal文件夹，路径：
按照文档下载相应的包，挑选自己想要的版本。
从部署脚本中截取安装docker的部分：
#!/bin/bash
echo "Please run this script as root. Because it will install docker and docker-compose.
If you have installed docker and docker-compose, please ignore this message.
And i use docker-compose version is 3.8, so please make sure your docker engine version is 19.03.0+."
echo
# check user is root
whoami=$(whoami)
if [ "$whoami" != "root" ]; then
echo "Please run as root."
exit 1
fi
# check docker is installed
# verlt 24.0.5 19.03.0 && echo "yes" || echo "no" # no
# this function check $1 is less than $2
versionLessThan() {
if [ "$1" = "$2" ]; then
return 1
else
# sort -V: natural sort of (version) numbers within text
[ "$1" = "$(echo -e "$1\n$2" | sort -V | head -n1)" ]
fi
}
if ! which docker >/dev/null 2>&1; then
echo "docker is not installed. Start install docker."
# install docker use offline package
cd docker-install || exit

如果当前机器已经安装docker了，那么我检查当前docker engine版本，我用的docker compose版本为3.8，因此我需要docker engine 大于等于 19.03.0
# check docekr engine version
docker_version=$(docker version --format '{{.Server.Version}}')
echo "docker engine version is $docker_version"
# if docker_version less than 19.03.0, exit
if versionLessThan "$docker_version" "19.03.0"; then
echo "docker engine version is less than 19.03.0, please upgrade docker engine."
exit 1

将docker镜像备份：docker save -o yourImage.tar company/yourImage:v1.0
将备份的tar上传到离线的机器，加载镜像：docker load -i yourImage.tar
镜像加载好后，就可以用docker compose启动容器了
我的docker compose：
version: "3.8"

mysql的数据文件不能和日志文件等放到一起，否则启动时会报错，说数据目录已经有文件
如果你有在初次部署时有对某些应用进行初始化的操作，比如我需要在初次部署时，将minio创建Access key，创建默认bucket，开启webhook。那么可以在minio容器启动后：
# check minio is running
if pgrep -x "minio" >/dev/null; then
echo "minio init..."
# minio deploy: create access key and secret key, create bucket, webhook event
docker exec -i minio bash < minioDeploy.sh
else
echo "minio is not running. This will influence file upload and download."
fi
这样会在容器中执行minioDeploy.sh脚本。
minioDeploy.sh脚本内容：
#!/bin/bash
# minio deploy: create access key and secret key, create bucket, webhook event
chmod +x /opt/bin/mc
cd /opt/bin || exit
mc alias set myminio http://127.0.0.1:9002 ROOTNAME CHANGEME123
mc admin user svcacct add --access-key "xFkEokGRAlwIs1234" --secret-key "jaz4FlvCDDKvbBuQYJ9NIohMUlRDsT132465789" myminio ROOTNAME
mc mb myminio/cogent
mc event add myminio/cogent arn:minio:sqs::PRIMARY:webhook --event put
mc event add myminio/cogent arn:minio:sqs::PRIMARY:webhook --event delete
