docker相关报错记录
docker info 报warning
Section titled “docker info 报warning”# WARNING: IPv4 forwarding is disabled. Networking will not work.# 解决办法:vi /etc/sysctl.conf# 或者vi /usr/lib/sysctl.d/00-system.conf# 添加如下代码: net.ipv4.ip_forward=1
# 重启network服务systemctl restart network
# 查看是否修改成功sysctl net.ipv4.ip_forward
# 如果返回为“ net.ipv4.ip_forward = 1 ”则表示成功了# 执行 docker info 时出现警告# WARNING: bridge-nf-call-iptables is disabled# WARNING: bridge-nf-call-ip6tables is disabled# 解决办法:
vi /etc/sysctl.conf# 在文件里添加下面两行代码:
net.bridge.bridge-nf-call-ip6tables = 1net.bridge.bridge-nf-call-iptables = 1# 然后 ESC 退出后 :wq 保存,执行下面代码:
sysctl -p# 再试一次 docker info 问题应该解决了使用docker stack deploy 时遇到image could not be accessed on a registry to record its digest
Section titled “使用docker stack deploy 时遇到image could not be accessed on a registry to record its digest”- 首先说一下遇到的坑,当执行命令时,会在work节点上pull配置文件中指定好的镜像,如果是DockerHub中存在的镜像则无问题,如果是私有镜像,就算是登录了也无法获取
- 解决办法:在stack deploy后添加 —with-registry-auth即可
