It simplifies debugging and provides a clean, colorized, human-readable report. 8 | 9 | ## Features 10 | 11 | - **Describe-like Output:** Quickly see essential details for a Pod or Deployment. 12 | - **Pod Discovery:** If you provide a Deployment, `kpeek` finds its Pods automatically. 13 | - **Logs (Optional):** View logs from each container in your Pods with color highlighting. 14 | - **Events (Optional):** Fetch resource-level and Pod-level events in a concise table. 15 | - **JSON Output:** Switch to machine-readable JSON for automated processing. 16 | 17 | ## Installation 18 | 19 | ### Using Go Install 20 | 21 | ```bash 22 | go install github.com/ourmallet/kpeek@latest 23 | ``` 24 | 25 | > [!NOTE] 26 | > - The above command does not embed an official release version in the binary. If you run `kpeek update` and your local version is unrecognized, kpeek may always see itself as outdated. You can still successfully update to the latest release, but your local binary won’t display an exact version string. 27 | > - You might need to add `$HOME/go/bin` to Your `$PATH` after installation 28 | 29 | ## Pre-Compiled Binaries 30 | 31 | For an officially versioned kpeek build, download a pre-built release binary. Place it in your PATH, and you’ll have the correct version string for self-updates. 32 | 33 | ### Build From Source (with Version Injection) 34 | 35 | ```bash 36 | git clone https://github.com/ourmallet/kpeek.git 37 | cd kpeek 38 | go build -ldflags "-X github.com/ourmallet/kpeek/cmd.version=v0.7.0" -o kpeek . 39 | ./kpeek --help 40 | ``` 41 | 42 | >[!NOTE] 43 | > Replace `v0.7.0` with the appropriate release version. This approach embeds the release version in the binary, which ensures that commands like kpeek update correctly compare the local version with the latest release. 44 | 45 | - Run With `go run` 46 | 47 | ```bash 48 | git clone https://github.com/ourmallet/kpeek.git 49 | cd kpeek 50 | go run main.go --help 51 | ``` 52 | 53 | ## Usage 54 | 55 | ```bash 56 | kpeek [resource/type-name] [flags] 57 | ``` 58 | 59 | ### Flags 60 | 61 | | Flag | Purpose | 62 | | ------------|------------| 63 | | `n, --namespace string` | Kubernetes namespace of the resource (default: default).| 64 | | `--json` | Output in JSON format. | 65 | | `--no-logs` | Skip retrieving container logs. | 66 | | `--include-events` | Include events in the output.| 67 | | `--log-tail int` | Display only the last N lines of logs (`0` for all) | 68 | | `--log-regex` | Regular expression to filter log lines | 69 | 70 | ## How to Update 71 | 72 | kpeek includes a built-in command that checks GitHub for a newer release and updates the local binary if one is found. To use it, simply run: 73 | 74 | ```bash 75 | kpeek update 76 | ``` 77 | 78 | If a newer version is available, kpeek will automatically download the latest release and replace your current binary. This makes staying up-to-date easy and requires no manual download or reinstallation. 79 | 80 | ## Running kpeek as a kubectl Plugin 81 | 82 | kpeek is designed to work seamlessly as a standalone CLI tool—but you can also run it as a kubectl plugin for a more native Kubernetes experience. Follow the steps below to set up and use kpeek as a kubectl plugin. 83 | 84 | ### Installation Steps 85 | 86 | 1. **Build or Download kpeek** 87 | 88 | - **Build from Source:** 89 | Run the following command in your kpeek project directory: 90 | 91 | ```bash 92 | go build -o kpeek . 93 | ``` 94 | 95 | - **Download Pre-Built Binary:** 96 | Alternatively, download the latest release binary from our [GitHub Releases](https://github.com/ourmallet/kpeek/releases). 97 | 98 | 2. **Rename the Binary** 99 | Kubectl recognizes plugins by the `kubectl-` prefix. Rename the kpeek binary: 100 | 101 | ```bash 102 | mv kpeek kubectl-kpeek 103 | ``` 104 | 105 | 3. **Place the Plugin in Your PATH** 106 | 107 | Ensure that the directory containing kubectl-kpeek is in your system’s PATH. For example, you can move it to /usr/local/bin: 108 | 109 | ```bash 110 | sudo mv kubectl-kpeek /usr/local/bin/ 111 | ``` 112 | 113 | If you prefer a custom directory, add that directory to your PATH in your shell configuration file (e.g., .bashrc or .zshrc). 114 | 115 | 4. **Verify Installation** 116 | 117 | Run the following command to ensure kubectl discovers the plugin: 118 | 119 | ```bash 120 | kubectl kpeek --help 121 | ``` 122 | 123 | You should see the kpeek help output, which confirms that the plugin is correctly installed. 124 | 125 | ### Additional Tips 126 | 127 | - **Pre-Built Binaries**: 128 | If you download a pre-built binary from GitHub releases, remember to rename it to kubectl-kpeek before moving it to a directory in your $PATH. 129 | 130 | - **Plugin Discovery**: 131 | Kubectl automatically discovers any executable named with the kubectl- prefix. No further configuration is necessary, but you can optionally create a plugin configuration file at $HOME/.kube/plugins.yaml if you want to document your installed plugins. 132 | 133 | - **Flag Compatibility**: 134 | All the flags available in the standalone kpeek (e.g., --no-logs, --include-events, --log-tail, --log-regex) work exactly the same when you run kpeek as a kubectl plugin. 135 | 136 | ## Contributing 137 | 138 | - Fork this repository and clone your fork. 139 | - Create a feature branch: git checkout -b feature/my-feature 140 | - Make changes and commit: git commit -m 'Add my feature' 141 | - Push to your fork: git push origin feature/my-feature 142 | - Open a Pull Request describing your changes. 143 | 144 | All contributions, bug reports, bug fixes, documentation improvements, enhancements, and ideas are welcome. 145 | 146 | ## License 147 | 148 | This project is licensed under the MIT License.
