Camel K CLI (kamel)

The Camel K command line interface, kamel, is the main entry point for running integrations on a Kubernetes cluster.

Releases of the Camel K CLI are available on:

Apache Mirrors (official): https://downloads.apache.org/camel/camel-k/
Github Releases: https://github.com/apache/camel-k/releases
Homebrew (Mac and Linux): https://formulae.brew.sh/formula/kamel

Running on macOS

Before running the CLI on macOS, it may be necessary to give adequate permissions for it to run.

It can either be done on the "Privacy & Security" panel in the System Settings or via command-line:

xattr -d com.apple.quarantine /path/to/kamel

Available Commands

Some of the most used commands are:

Table 1. Useful Commands
Name	Description	Example
`help`	Obtain the full list of available commands	`kamel help`
`run`	Run an integration on Kubernetes	`kamel run Routes.java`
`debug`	Debug a remote integration using a local debugger	`kamel debug my-integration`
`get`	Get integrations deployed on Kubernetes	`kamel get`
`describe`	Get detailed information on a resource	`kamel describe integration routes`
`log`	Print the logs of a running integration	`kamel log routes`
`delete`	Delete integrations deployed on Kubernetes	`kamel delete routes`
`bind`	Bind Kubernetes resources, such as Kamelets, in an integration flow.	`kamel bind timer-source -p "source.message=hello world" channel:mychannel`
`install`	Install Camel K on a Kubernetes cluster	`kamel install`
`rebuild`	Clear the state of integrations to rebuild them.	`kamel rebuild --all`
`reset`	Reset the Camel K installation	`kamel reset`
`uninstall`	Uninstall Camel K from a Kubernetes cluster	`kamel uninstall`
`version`	Display client version	`kamel version`

The list above is not the full list of available commands. You can run kamel help to obtain the full list. Each command also takes the --help as option to output more information, e.g.:

$ kamel run --help

Global Flags

While each command has a dedicated set of flags, there are global flags that are available to every command:

Table 2. Global Flags
Flag	Description	Example
`--kube-config PATH`	Path to the config file to use for CLI requests	`kamel install --kube-config ~/.kube/config`
`-h` or `--help`	Help for `kamel`, or the command	`kamel run --help`
`-n` or `--namespace NAME`	Namespace to use for all operations	`kamel get --namespace NAME`

For command-specific flags, run --help with the command to obtain the full list, e.g.:

$ kamel <command> --help

Modeline

Some command options in the CLI can be also specified as modeline in the source file, take a look at the Modeline section for more information.

Image Registry

The CLI can be used to upload content to the Image Registry. To do so, the registry options need to be correctly set during installation. If the Image Registry uses a custom certificate authority then it needs to be trusted by the CLI see SSL_CERT_FILE. If the Image registry uses authentication then it should be configured correctly in $HOME/.docker/config.json; see Docker Credentials store].
