现象描述
将镜像推送到私有仓库，出现错误“received unexpected HTTP status: 500 Internal Server Error”
[root@docker ~]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE docker.io/nginx 1.18.0 b5390718bd8e 6 days ago 132.8MB docker.io/registry latest 2d4f4b5309b1 4 months ago 26.22MB [root@docker ~]# docker tag docker.io/nginx:1.18.0 192.168.1.31:5000/nginx:1.18.0[root@docker ~]#docker push 192.168.1.31:5000/nginx:1.18.0The push refers to a repository [192.168.1.31:5000/nginx] 350c442bd17b: Retrying in 1second 11ebfd90bb46: Retrying in 1second 77a84e783709: Retrying in 1second 8ea8cf9de1a9: Retrying in 1second d0fe97fa8b8c: Retrying in 1second received unexpected HTTP status: 500 Internal Server Error
解决办法：
关闭SELinux。
临时关闭SELinux：
[root@docker ~]# setenforce 0永久关闭，重启后生效：
[root@docker ~]# sed -i 's#SELINUX=enforcing#SELINUX=disabled#g' /etc/selinux/config [root@docker ~]# egrep '^SELINUX=' /etc/selinux/config SELINUX=disabled
关闭SELinux 之后， docker push 就可以了。
