我正在尝试安装 Docker Truster Registry (DTR)。我正在执行以下命令:
docker run -it --rm \
docker/dtr install \
--ucp-url https://10.000.000.125 \
--ucp-node node123 \
--dtr-external-url https://10.000.000.97 \
--ucp-username admin --ucp-password admin \
--ucp-ca "$(cat ucp-ca.pem)" \
我收到以下错误:
ERRO[0000] Make sure that there is a node in your UCP cluster where port 80 and port 443 are open. Also confirm that all UCP node have the DTR images or can obtain them from Docker Hub.
FATA[0000] Problem running container 'dtr-phase2' from image 'docker/dtr:2.0.2': Couldn't create container 'dtr-phase2' from image 'docker/dtr:2.0.2': Error response from daemon: Unable to find a node that satisfies the following conditions
[available container slots]
[node==node123 node!=node123]
我能够从我尝试安装 DTR 的位置 ping 服务器。我不知道那个问题是什么意思。我很感激任何帮助
