Dockly – Manage Docker Containers From Terminal
|
||||
======
|
||||
|
||||
![][1]
|
||||
|
||||
A few days ago, we published a guide which covered almost all details you ever need to know to [**getting started with Docker**][2]. In that guide, we have shown you how to create and manage Docker containers in detail. There are also some non-official tools available for managing Docker containers. If you’ve looked at our old archives, you might have stumbled upon two web-based tools namely [**“Portainer”**][3] and [**“PiCluster”**][4]. Both of them makes the Docker management task much easier and simpler from a web browser. Today, I came across yet another Docker management tool named **“Dockly”**.
|
||||
|
||||
Unlike the aforementioned tools, Dockly is a TUI (text user interface) utility to manage Docker containers and services from the Terminal in Unix-like systems. It is free, open source tool built with **NodeJS**. In this brief guide, we will see how to install Dockly and how to manage Docker containers from command line.
|
||||
|
||||
### Installing Dockly
|
||||
|
||||
Make sure you have installed NodeJS on your Linux box. If you haven’t installed it yet, refer the following guide.
|
||||
|
||||
* [**How To Install NodeJS On Linux**][5]
|
||||
|
||||
|
||||
|
||||
Once NodeJS is installed, run the following command to install Dockly:
|
||||
|
||||
```
|
||||
# npm install -g dockly
|
||||
```
|
||||
|
||||
### Manage Docker Containers With Dockly From Terminal
|
||||
|
||||
Managing Docker containers with Dockly is easy! All you have to do is to open the terminal and run the following command:
|
||||
|
||||
```
|
||||
# dockly
|
||||
```
|
||||
|
||||
Dockly will will automatically connect to your localhost docker daemon through the unix socket and display the list of running containers in the Terminal as shown below.
|
||||
|
||||
![][6]
|
||||
|
||||
Manage Docker Containers Using Dockly
|
||||
|
||||
As you can see in the above screenshot, Dockly displays the following information of running containers on the top:
|
||||
|
||||
* Container ID,
|
||||
* Name of the container(s),
|
||||
* Docker image,
|
||||
* Command,
|
||||
* State of the running container(s),
|
||||
* Status.
|
||||
|
||||
|
||||
|
||||
On the top right side, you will see the CPU an Memory utilization of containers. Use UP/DOWN arrow keys to move between Containers.
|
||||
|
||||
At the bottom, there are few keyboard shortcut keys to do various docker management tasks. Here are the list of currently available keyboard shortcuts:
|
||||
|
||||
* **=** – Refresh the Dockly interface,
|
||||
* **/** – Search the containers list view,
|
||||
* **i** – Display the information about the currently selected container or service,
|
||||
* **< RETURN>** – Show logs of the current container or service,
|
||||
* **v** – Toggle between Containers and Services view,
|
||||
* **l** – Launch a /bin/bash session on the selected Container,
|
||||
* **r** – Restart the selected Container,
|
||||
* **s** – Stop the selected Container,
|
||||
* **h** – Show HELP window,
|
||||
* **q** – Quit Dockly.
|
||||
|
||||
|
||||
|
||||
##### **Viewing information of a container**
|
||||
|
||||
Choose a Container using UP/DOWN arrow and press **“i”** to display the information of the selected Container.
|
||||
|
||||
![][7]
|
||||
|
||||

|
||||
|
||||
##### Restart Containers
|
||||
|
||||
If you want to restart your Containers at any time, just choose it and press **“r”** to restart.
|
||||
|
||||
![][8]
|
||||
|
||||
Restart Docker containers
|
||||
|
||||
##### Stop/Remove Containers and Images
|
||||
|
||||
We can stop and/or remove one or all containers at once if they are no longer required. To do so, press **“m”** to open **Menu**.
|
||||
|
||||
![][9]
|
||||
|
||||
Stop, remove Docker containers and images
|
||||
|
||||
From here, you can do the following operations.
|
||||
|
||||
* Stop all Docker containers,
|
||||
* Remove selected container,
|
||||
* Remove all containers,
|
||||
* Remove all Docker images etc.
|
||||
|
||||
|
||||
|
||||
##### Display Dockly help section
|
||||
|
||||
If you have any questions, just press **“h”** to open the help section.
|
||||

For more details, refer the official GitHub page given at the end.
|
||||
|
||||
And, that’s all for now. Hope this was useful. If you spend a lot of time working with Docker containers, give Dockly a try and see if it helps.

Dockly - 从终端管理 Docker 容器
|
||||
======
|
||||
|
||||
![][1]
|
||||
|
||||
几天前，我们发布了一篇指南，其中涵盖了[**开始使用 Docker**][2] 时需要了解的几乎所有细节。在该指南中，我们向你展示了如何详细创建和管理 Docker 容器。还有一些非官方工具可用于管理 Docker 容器。如果你看过我们以前的文字，你可能会看到两个基于网络的工具，[**“Portainer”**][3] 和 [**“PiCluster”**][4]。它们都使得 Docker 管理任务在 Web 浏览器中变得更加容易和简单。今天，我遇到了另一个名为 **“Dockly”** 的 Docker 管理工具。
|
||||
|
||||
与上面的工具不同，Dockly 是一个 TUI（文本界面）程序，用于在类 Unix 系统中从终端管理 Docker 容器和服务。它是使用 **NodeJS** 编写的免费开源工具。在本简要指南中，我们将了解如何安装 Dockly 以及如何从命令行管理 Docker 容器。
|
||||
|
||||
### 安装 Dockly
|
||||
|
||||
确保已在 Linux 上安装了 NodeJS。如果尚未安装，请参阅以下指南。
|
||||
|
||||
* [**如何在 Linux 上安装 NodeJS**][5]
|
||||
|
||||
|
||||
|
||||
安装 NodeJS 后，运行以下命令安装 Dockly：
|
||||
|
||||
```
|
||||
# npm install -g dockly
|
||||
```
|
||||
|
||||
### 使用 Dockly 在终端管理 Docker 容器
|
||||
|
||||
使用 Dockly 管理 Docker 容器非常简单！你所要做的就是打开终端并运行以下命令：
|
||||
|
||||
```
|
||||
# dockly
|
||||
```
|
||||
|
||||
Dockly 将通过 unix 套接字自动连接到你的本机 docker 守护进程，并在终端中显示正在运行的容器列表，如下所示。
|
||||
|
||||
![][6]
|
||||
|
||||
使用 Dockly 管理 Docker 容器
|
||||
|
||||
正如你在上面的截图中看到的，Dockly 在顶部显示了运行容器的以下信息：
|
||||
|
||||
* 容器 ID，
|
||||
* 容器名称，
|
||||
* Docker 镜像，
|
||||
* 命令，
|
||||
* 运行中容器的状态，
|
||||
* 状态。
|
||||
|
||||
|
||||
|
||||
在右上角，你将看到容器的 CPU 和内存利用率。使用向上/向下箭头键在容器之间移动。
|
||||
|
||||
在底部，有少量的键盘快捷键来执行各种 Docker 管理任务。以下是目前可用的键盘快捷键列表：
|
||||
|
||||
* **=** - 刷新 Dockly 界面，
|
||||
* **/** - 搜索容器列表视图，
|
||||
* **i** - 显示有关当前所选容器或服务的信息，
|
||||
* **回车** - 显示当前容器或服务的日志，
|
||||
* **v** - 在容器和服务视图之间切换，
|
||||
* **l** - 在选定的容器上启动 /bin/bash 会话，
|
||||
* **r** - 重启选定的容器，
|
||||
* **s** - 停止选定的容器，
|
||||
* **h** - 显示帮助窗口，
|
||||
* **q** - 退出 Dockly。
|
||||
|
||||
|
||||
|
||||
##### **查看容器的信息**
|
||||
|
||||
使用向上/向下箭头选择一个容器，然后按 **“i”** 以显示所选容器的信息。
|
||||
|
||||
![][7]
|
||||
|
||||
查看容器的信息
|
||||
|
||||
##### 重启容器
|
||||
|
||||
如果你想随时重启容器，只需选择它并按 **“r”** 即可重新启动。
|
||||
|
||||
![][8]
|
||||
|
||||
重启 Docker 容器
|
||||
|
||||
##### 停止/删除容器和镜像
|
||||
|
||||
如果不再需要容器，我们可以立即停止和/或删除一个或所有容器。为此，请按 **“m”** 打开**菜单**。
|
||||
|
||||
![][9]
|
||||
|
||||
停止，删除 Docker 容器和镜像
|
||||
|
||||
在这里，你可以执行以下操作。
|
||||
|
||||
* 停止所有 Docker 容器，
|
||||
* 删除选定的容器，
|
||||
* 删除所有容器，
|
||||
* 删除所有 Docker 镜像等。
|
||||
|
||||
|
||||
|
||||
##### 显示 Dockly 帮助部分
|
||||
|
||||
如果你有任何疑问，只需按 **“h”** 即可打开帮助部分。
|
||||

|
||||
|
||||
就是这些了。希望这篇文章有用。如果你一直在使用 Docker 容器，请试试 Dockly，看它是否有帮助。
