我们想在开始部署之前自动检查公共注册中心(Docker Hub)中是否存在图像.使用v1 API,我们只会查询https://index.docker.io/v1/repositories/gliderlabs/alpine/tags/3.2示例.
但是现在注册表的官方API是v2,检查公共注册表中图像是否存在的官方方法是什么?

无法kubectl在 Mac 上完成 bash。我bash-completion用brewie安装brew install bash-completion,然后按照安装说明,将其添加到~/.bash_profile:
if [ -f $(brew --prefix)/etc/bash_completion ]; then

kubectl -bash: _init_completion: command not found但重新获取配置文件后仍然出现错误。
我想知道在给定时间段内我们向 InfluxDB 发送了多少事件。如果我使用以下查询SELECT COUNT(value) FROM /./ WHERE time > now() - 1h GROUP BY time(10m),我会为每个指标分组,但我想要所有指标的总数。
如果我使用SELECT COUNT(*) FROM /./ WHERE time > now() - 1h GROUP BY time(10m),我会收到一个错误:
服务器返回错误:count() 中的预期字段参数
