ubuntu - Docker Compose 无法使用 Podman 构建

Question

如果我为服务拉取图像，Docker compose 将与 podman 一起使用，但在我尝试构建图像时将无法使用。
Dockerfile

FROM docker.io/hello-world


$ docker build --tag uscm5 .
STEP 1: FROM docker.io/hello-world
STEP 2: COMMIT uscm5
--> d1165f22123
Successfully tagged localhost/uscm5:latest
Successfully tagged docker.io/library/hello-world:latest
d1165f2212346b2bab48cb01c1e39ee8ad1be46b87873d9ca7a4e434980a7726

docker-compose.yml
使用图像配置而不是构建，它工作得很好。

services:
  web:
    build: .
    # image: docker.io/hello-world 


$ docker-compose up
Building web

我的环境和程序版本似乎正确:

$ docker-compose -v && podman -v && lsb_release -r
docker-compose version 1.29.2, build 5becea4c
podman version 3.2.3
Release:        21.04

$ printenv | grep -e DOCKER -e COMPOSE
DOCKER_HOST=unix:///run/user/1000/podman/podman.sock

我错过了什么？

Answer 1

设置COMPOSE_DOCKER_CLI_BUILD=0就是它所在的位置 - 谢谢@Luap99 在 GitHub。 https://github.com/containers/podman/issues/11052
Docker Compose 使用 Docker CLI 而不是 DOCKER_HOST 处的套接字。如果我有 alias docker=podman，也许我不会注意到但与 COMPOSE_DOCKER_CLI_BUILD=0将使用 docker 客户端而不是 CLI。
