docker - 如何使用 docker 安装 guacenc？

Question

我用docker安装了guacamole和guacadmin，所以我也想用docker安装guacenc，但是没找到资料。

其实我还没有找到其他安装guacenc的方法。如果有人知道，我希望我能得到答案。

非常感谢

Answer 1

如果guacamole并且guacadmin可以安装在 linux/windows/Mac OS 上，那么它可以在 docker 中运行。

这是guacamoledockerhub上的官方docker镜像，大家可以试试。

也检查一下。

更新：

要在 centos docker 映像中安装 guacenc，您需要安装必要的软件包，如此处所述。

引用此链接中的声明。

guacamole-server 提供的用于将屏幕录制转换为视频的 guacenc 实用程序依赖于 FFmpeg，并且只有在至少安装了 FFmpeg 提供的 libavcodec、libavutil 和 libswscale 库后才能构建。

---

guacenc 使用 FFmpeg 提供的 libavcodec、libavutil 和 libswscale 库在翻译 Guacamole 会话记录时对视频流进行编码。如果没有 FFmpeg，guacenc 实用程序将根本无法构建。

您需要使用安装这些软件包，yum install以便guacenc可以构建和安装实用程序。

希望这可以帮助。

此 dockerfile 仅供参考。谢谢

# This is a Dockerfile to build the docker image including guacenc service and ffmpeg utility.
# To reduce docker image size, utilize multi-stage build method and copy shared library file required while executing guacenc. 
# Copying shared library method is inspired by this thread "https://gist.github.com/bcardiff/85ae47e66ff0df35a78697508fcb49af"

# Encode existing session recordings to .m4v:
# $ docker exec -it guac_encoder guacenc -f /recordings/file-name-to-encode

# Convert .m4v to .mp4:
