在使用 docker pull 拉取镜像时,遇到如下报错:
Error response from daemon: toomanyrequests: You have reached your pull rate limit. You may increase the limit by authenticating and upgrading: https://www.docker.com/increase-rate-limit
2020 年 11 月 20 日,Docker Hub 基于个人 IP 地址对匿名和免费认证的用户进行了镜像拉取次数的限制。
对于匿名用户,限制设置为每个 IP 地址每 6 小时 100 次拉取。
对于经过身份验证的用户,每 6 小时 200 次拉取。
那么如何查看我们剩余的拉取次数呢?
匿名用户获取令牌:
TOKEN=$(curl "https://auth.docker.io/token?service=registry.docker.io&scope=repository:ratelimitpreview/test:pull" | jq -r .token)
认证用户获取令牌:
TOKEN=$(curl --user 'username:password' "https://auth.docker.io/token?service=registry.docker.io&scope=repository:ratelimitpreview/test:pull" | jq -r .token)
root@nianyu-virtual-machine:~# curl --head -H "Authorization: Bearer $TOKEN" https://registry-1.docker.io/v2/ratelimitpreview/test/manifests/latest

这意味着我的限制是每 21600 秒(6 小时)拉取 200 次,我还可以拉取 200次。
