Installing on Kubernetes¶

Prerequisites

Supports installation on both ARM and x86 architectures.

Choose DataWay Data Gateway Address¶

DataWay is the data gateway for TrueWatch. All data reported by collectors to TrueWatch must pass through the DataWay gateway.

Run the following script to download¶

wget https://static.guance.com/datakit-v2/datakit.yaml

Modify the datakit.yaml file¶

Configure the DataWay Data Gateway Address

- name: ENV_DATAWAY
  value: https://openway.guance.com?token=tkn_7f5********fda8681

DataKit enables host-related collectors by default

- name: ENV_DEFAULT_ENABLED_INPUTS
  value: cpu,disk,diskio,mem,swap,system,hostobject,net,host_processes,container

If you need to enable more collectors, simply append them to the above configuration. Of course, you can also remove certain collectors from this list.

Collectors enabled by default in TrueWatch:

Collector Name	Description
`cpu`	Collects the host's CPU usage
`disk`	Collects disk usage
`diskio`	Collects the host's disk IO
`mem`	Collects the host's memory usage
`swap`	Collects Swap memory usage
`system`	Collects the host operating system load
`net`	Collects host network traffic
`host_processes`	Collects the list of resident processes (alive for more than 10 minutes) on the host
`hostobject`	Collects basic host information (such as operating system information, hardware information, etc.)
`container`	Collects possible container objects and container logs on the host

In DaemonSet mode, DataKit also supports multiple environment variable configurations.

See More Environment Variables.

Execute the following command to install DataKit¶

kubectl apply -f datakit.yaml

After installation, the system will automatically create a DaemonSet deployment for DataKit.

Check DataKit Running Status¶

kubectl get pod -n datakit
