docker - 解码内容错误 : invalid character '<' looking for beginning of value

Question

我设置了 Artifactory Pro Docker 镜像版本 5.4.5。我也在使用 Nginx，并使用自签名证书启用了 HTTPS。当我尝试运行 docker pull 命令时，出现错误:

[root@tom ~]# docker pull docker-dev.artifactory.company.com/docker/hello-world
Using default tag: latest
Error response from daemon: error unmarshalling content: invalid character '<' looking for beginning of value

docker login 工作正常。

[root@tom ~]# docker login docker-dev.artifactory.company.com --username admin --password password
WARNING! Using --password via the CLI is insecure. Use --password-stdin.
WARNING! Your password will be stored unencrypted in /root/.docker/config.json.
Configure a credential helper to remove this warning. See
https://docs.docker.com/engine/reference/commandline/login/#credentials-store

Login Succeeded

在 Artifactory 服务器上，

$ cat /data/nginx/logs/access.log

我确实检查了 official guide和其他一些在线文章，但自最近两天以来无法正常工作。非常感谢您的帮助。

不确定这是否对以后的人有帮助，但当图像名称中的地址错误时，我遇到了同样的错误。在我的例子中，我使用了 bintray.com/jfrog/artifactory-pro:latest，而不是 jfrog-docker-reg2.bintray.io/jfrog/artifactory-pro:latest
