ICP 2.1 Beta 2 无法足够快地创建 Cloudant DB

Question

当运行来自 the installation instructions 的以下命令时：

sudo docker run --net=host -t -e LICENSE=accept -v $(pwd):/installer/cluster \
            ibmcom/icp-inception:2.1.0-beta-2-ee install

创建 Cloudant 数据库的任务超时：

容器仍在 /usr/bin/python /usr/bin/ansible-playbook -e @cluster/config.yaml playbook/site.yaml 中使用 CPU，所以我认为它仍在安装中。如何增加重试次数？

Answer 1

这通常意味着 cloudant db 准备时间太长，到那时，已达到 20 次重试限制。卸载 ICP 2.1 beta2 并安装它通常可以解决此问题。在 ICP 2.1 beta3 中，它会增加超时时间。

如果这不起作用，您可以检查以下内容：

docker exec -it <cloudant container> bash

现在在容器内，检查数据库状态：

cast cluster status -p $ADMIN_PASSWORD

也可以检查：

docker logs <long cloudant container name>

再次安装ICP beta2之前，检查是否 docker volume ls 已清理。

Answer 2

运行命令

docker info | grep -i cgroup

你应该会看到

Cgroup Driver: systemd

...通过添加

行与 ICP 中的匹配

kubelet_extra_args: ["--cgroup-driver=systemd"]

到ICPconfig.yaml

Answer 3

在某些情况下，我们发现基于 Cloudant 的 ICP 数据存储的大小需要一段时间才能下载。您是否考虑过将映像预拉到您的主机上？

docker pull ibmcom/icp-datastore:{version}

您需要在每个 master 上执行此操作（但不是在工作节点上）。
