Inventory CLI (ic)

This is the CLI used to interact with k8s-inventory-server.

Installation

tag=$(
    curl --silent -H "Accept: application/vnd.github.v3+json" \
    https://api.github.com/repos/neticdk-k8s/ic/releases/latest \
    | jq -r .tag_name
)

curl -L https://github.com/neticdk-k8s/ic/releases/download/${tag}/ic-${tag}-$(uname -s|tr A-Z a-z)-$(uname -m).tar.gz \
    | tar xzf - /usr/local/bin/ic

make install

Introduction

Basic usage:

ic COMMAND [flags]

Authentication

Most commands require authentication. By default, browser based OICD authentication will be used.

If you want to use keyboard based OICD authentication you can use the --oidc-grant-type authcode-keyboard flag.

ic will try to refresh the token on every run.

Tokens are cached in the default user cache directory for the Operating System ic is running on:

• ~/Library/Caches/ic/oidc-login/ on MacOS
• $XDG_CACHE_HOME (typically $HOME/.cache) on Linux
• %LocalAppData% on Windows

Output

Commands will output log messages and errors to stderr and normal output to stdout.

The default format is text which in usually means tables. In most cases commands will support json output via the --output-format json flag.

Colors and other flashy things are disabled while running in a non-interactive environment (e.g. when redirecting output to a log file). This can be controlled via the --interactive flag.

If you don't want headers printed you can use the --no-headers flag. This can be useful for piping output to other commands.

Commands and Usage

See docs/ic.md for more documentation on the commands.

You may also run ic help.

Development

Configuration for Local Development

You might want to create a configuration file named ic.toml in the root directory that looks something like this:

log-level="debug"
oidc-issuer-url="http://localhost:8080/realms/test"
api-server="http://localhost:8087"

Using api-token and curl with the API server

Use it like this:

curl -H "Authorization: Bearer $(bin/ic api-token 2>/dev/null)" http://localhost:8087/clusters | jq .

Code Generation

Mocks

Interface mocks are generated using mockery

The command used is:

mockery --with-expecter --inpackage --name <interface name>

OpenAPI Client Code

The inventory server provides an OpenAPI 2.0 spec.

We use oapi-codegen to generate the client code. See docs/openapi.md.
