使用:
我有这个Dockerfile:
FROM fedora:30
ENV LANG C.UTF-8
RUN dnf upgrade -y \
&& dnf install -y \
openssh-clients \
openvpn \
slirp4netns \
&& dnf clean all
CMD ["openvpn", "--config", "/vpn/ovpn.config", "--auth-user-pass", "/vpn/ovpn.auth"]
我使用的是哪个版本
podman build -t peque/vpn .
现在,为了能够成功运行它,我必须解决一些SELinux问题(请参阅Connect to VPN with Podman)。
sudo dnf install udica
我为VPN容器定义了此ovpn_container.cil
自定义策略:
(block ovpn_container
(blockinherit container)
(blockinherit restricted_net_container)
(allow process process (capability (chown dac_override fsetid fowner mknod net_raw setgid setuid setfcap setpcap net_bind_service sys_chroot kill audit_write net_admin)))
(allow process default_t (dir (open read getattr lock search ioctl add_name remove_name write)))
(allow process default_t (file (getattr read write append ioctl lock map open create)))
(allow process default_t (sock_file (getattr read write append open)))
(allow process tun_tap_device_t (chr_file (ioctl open read write)))
(allow process self (netlink_route_socket (nlmsg_write)))
(allow process unreserved_port_t (tcp_socket (name_connect)))
)
我通过以下方式应用该政策
:sudo semodule -r ovpn_container
sudo semodule -i ovpn_container.cil /usr/share/udica/templates/{base_container.cil,net_container.cil}
现在,我可以使用以下命令成功运行容器了:
podman run -v $(pwd):/vpn:Z --cap-add=NET_ADMIN --device=/dev/net/tun --security-opt label=type:ovpn_container.process -it peque/vpn
容器运行后,我在容器内打开一个终端,我要从该终端ssh
到远程服务器:
podman exec -it container_name bash
从容器中,我可以成功ssh
到远程服务器,但前提是它们不在VPN内。
当我尝试ssh
到VPN中的服务器时,它卡住了一段时间,然后抛出此错误:
$ ssh server.domain.com
ssh: connect to host server.domain.com port 22: Connection refused
kex_exchange_identification: Connection closed by remote host
我可能会缺少什么?
