**harbor登录时报如下错误： **
[root@localhost TDFW-publish-tar]# docker login --username=user1 192.168.2.10:8090 --password user1_pass WARNING! Using --password via the CLI is insecure. Use --password-stdin. Error response from daemon: Get "http://192.168.2.10:8090/v2/": error parsing HTTP 404 response body: invalid character '<' looking for beginning of value: "<html>\n<head>\n<meta http-equiv=\"Content-Type\" content=\"text/html; charset=UTF-8\"/>\n<title>Error 404 Not Found</title>\n</head>\n<body><h2>HTTP ERROR 404</h2>\n<p>Problem accessing /service/token. Reason:\n<pre> Not Found</pre></p><hr><i><small>Powered by Jetty://</small></i><hr/>\n\n</body>\n</html>\n"此时查看/etc/docker/daemon.json 是否已经设置
[root@localhost TDFW-publish-tar]# cat /etc/docker/daemon.json { "insecure-registries":["192.168.2.10:8090"], "registry-mirrors": ["http://hub-mirror.c.163.com"], "data-root": "/data/docker-home" }从上面可以看到已经设置了，想到之前对harbor的配置信息做了调整(将内网地址映射成了外网地址)：
vim /opt/harbor/common/config/core/env EXT_ENDPOINT=http://1.1.1.1:18003后面由于关闭了外网映射所以导致了登陆失败，此时只需要将其改为内网地址即可，具体如下：
EXT_ENDPOINT=http://172.16.16.16:10241进入harbor目录修改
# 容器内端口8080，外部映射端口8090 [root@localhost harbor]# ls common docker-compose.yml harbor.v2.3.4.tar.gz harbor.yml.tmpl install.sh LICENSE prepare common.sh harbor_data harbor.yml https isunland-pms-nacos-0.0.1.tar log-harbor [root@localhost harbor]# vim common/config/core/env #EXT_ENDPOINT=http://192.168.2.10:8080 #改成》 EXT_ENDPOINT=http://192.168.2.10:8090此时重启harbor即可
docker-compose down
docker-compose up -d
此时再次登陆问题解决了
