Question

我在RHEL7中安装Podman后配置了Subuid和Subgid

我创建了一个简单的 Dockerfile 来打印 hello world 并尝试构建映像。我的 Dockerfile

FROM alpine
CMD ["echo", "Hello World"]

为了测试我在命令下运行

Podman build -t imagename .

我看到收到以下错误。

STEP 1: FROM alpine
Error: error creating build container: The following failures happened while trying to pull image specified by "alpine" based on search registries in /etc/containers/registries.conf:
* "localhost/alpine": Error initializing source docker://localhost/alpine:latest: error pinging docker registry localhost: Get https://localhost/v2/: dial tcp [::1]:443: connect: connection refused

我是否缺少任何配置？

谢谢

Answer 1

建议您先在注册表中搜索您的图片

podman search alpine

您应该获得可用图像列表。选择您想要的一个 - 版本、名称、标签等并将其放入 dockerfile 中。

要确保它可以访问，请手动“拉”

podman pull alpine<version,tag>

Answer 2

您是否仍在运行和/或安装了 docker？

首先停止docker Daemon

 sudo systemctl stop docker

或

 sudo service docker stop

然后卸载docker Ubuntu 在这里，但你需要什么都可以谷歌：D

sudo apt-get remove docker docker-engine docker.io containerd runc

再试一次，

如果其他失败，现在尝试刷新安装 podman

sudo --reinstall install podman
