解压缩最简单的Dockerfile:找不到文件

我是一个新的docker用户.我花了很多时间在一个错误上,Dockerfile非常简短,但我无法解决这个问题.

我正在尝试下载tar文件,并将其解压缩

这是我的Dockerfile(每次尝试都不在Dockerfile中,同时为了简单起见我将它们放在一起)

FROM ubuntu:latest

# 1st try
ADD https://download.gnome.org/sources/glib/2.52/glib-2.52.1.tar.xz /tmp/
RUN ls -lah /tmp/glib-2.52.1.tar.xz
ADD /tmp/glib-2.52.1.tar.xz /tmp

# 2nd try
ADD https://download.gnome.org/sources/glib/2.52/glib-2.52.1.tar.xz /tmp/
RUN ls -lah /tmp/glib-2.52.1.tar.xz
RUN tar -C /tmp/ -xf /tmp/glib-2.52.1.tar.xz

# 3rd try
WORKDIR /tmp/
RUN wget https://download.gnome.org/sources/glib/2.52/glib-2.52.1.tar.xz
RUN ls -lah glib-2.52.1.tar.xz
RUN tar -xf glib-2.52.1.tar.xz

# 4th try
RUN wget https://download.gnome.org/sources/glib/2.52/glib-2.52.1.tar.xz -O /tmp/glib-2.52.1.tar.xz
RUN ls -lah /tmp/glib-2.52.1.tar.xz
ADD /tmp/glib-2.52.1.tar.xz /tmp

# 5th try
RUN wget https://download.gnome.org/sources/glib/2.52/glib-2.52.1.tar.xz -O /tmp/glib-2.52.1.tar.xz
RUN ls -lah /tmp/glib-2.52.1.tar.xz
RUN tar -C /tmp/ -xf /tmp/glib-2.52.1.tar.xz

我尝试了所有可能的事情,使这个文件beign下载并取消归档.

仅在最后一步命令(unarchive,步骤4)上发生错误.

我基本上尝试了第五次尝试在我的电脑上运行:

$> wget https://download.gnome.org/sources/glib/2.52/glib-2.52.1.tar.xz -O /tmp/glib-2.52.1.tar.xz
$> tar -C /tmp/ -xf /tmp/glib-2.52.1.tar.xz
$> ls /tmp/glib*
glib-2.52.1 glib-2.52.1.tar.xz

这是我使用tar时的输出:

$> sudo docker build -t gtk --no-cache .

The command '/bin/sh -c tar -C /tmp/ -xf /tmp/glib-2.52.1.tar.xz' returned a non-zero code: 2

这是我使用ADD时的输出:

[...] # same output

Step 4/5 : ADD /tmp/glib-2.52.1.tar.xz /tmp/
lstat tmp/glib-2.52.1.tar.xz: no such file or directory

谢谢你的帮助!

请务必仔细阅读输出以获取提示:

tar (child): xz: Cannot exec: No such file or directory

您缺少xz-utils处理xz存档所需的映像中的包.尝试:

RUN apt-get install xz-utils && tar -C /tmp/ -xf /tmp/glib-2.52.1.tar.xz
