在 MacOS 上以 podman 作为后端运行 docker-compose

Question

我正在尝试在我的本地计算机 (MacOS) 上运行带有 podman 后端的 docker-compose CLI。 这是我所做的：

1. 使用 brew 安装 podman： brew install podman
2. 初始化 podman 机器： podman machine init
3. 启动机器： podman machine start

运行 podman version 给我这个：

Client:
Version:      3.4.4
API Version:  3.4.4
Go Version:   go1.17.6
Built:        Wed Dec  8 19:41:11 2021
OS/Arch:      darwin/amd64

Server:
Version:      3.4.4
API Version:  3.4.4
Go Version:   go1.16.8
Built:        Wed Dec  8 22:45:07 2021
OS/Arch:      linux/amd64

我为 podman 创建了一个符号链接 ( ln -s podman docker )，所以运行docker version给我相同的结果，我实际上可以使用docker run来运行容器，即使没有安装 docker。

之后我使用以下命令安装了 docker-compose：

sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

sudo chmod +x /usr/local/bin/docker-compose      

docker-compose version给我这个：

docker-compose version 1.29.2, build 5becea4c
docker-py version: 5.0.0
CPython version: 3.9.0
OpenSSL version: OpenSSL 1.1.1h  22 Sep 2020

问题是docker-compose up test无法正常工作，因为 docker-compose 似乎找不到要连接的 docker 主机或以某种方式被阻止，有人知道如何解决这个问题吗：

Answer 2

你安装了 podman-mac-helper 吗？

sudo /opt/homebrew/Cellar/podman/4.0.2/bin/podman-mac-helper install

docker-compose v2.3.4 在运行 macOS Monterey 的 MacBook Pro M1 上与 Podman v4.0.2 一起工作得很好，只要你安装 podman-mac-helper（这使得 /var/run/docker.sock 可用。）
