docker 本地注册表“exec:\”htpasswd\”：在 $PATH 中找不到可执行文件”

Question

直到最近这工作正常

docker run --entrypoint htpasswd registry:2 -Bbn myuser  mypwd  > /my/registry2/reg/hub/auth/htpasswd

现在它出错了

docker: Error response from daemon: OCI runtime create failed: container_linux.go:349: starting container process caused "exec: \"htpasswd\": executable file not found in $PATH": unknown.

这是在带有 docker 的 Ubuntu 18.04 和 20.04 上

Answer 1

如果您将本地 docker 注册表固定到，它将继续工作

registry:2.7.0

而不是仅使用registry:2它来获取最新版本 2，这可悲的是已损坏

有关详细信息，请参见 https://github.com/docker/distribution-library-image/commit/ab00e8dae12d4515ed259015eab771ec92e92dd4（他们删除了包 apache2-utils）和 https://github.com/GoogleContainerTools/jib/pull/2538/commits/2538/commits/2538/commits/2538/commits/2538/259015eab771ec92e92d4 和 https://github.com/GoogleContainerTools/jib/pull/2539，如https://github.com/docker/distribution-library-image/issues/106 中所述

或者，您可以使用以下命令安装二进制 htpasswd，而不是从 registry:2 中执行 htpasswd

apt-get install apache2-utils # thankfully this is NOT the apache server

并使用语法

htpasswd -Bbn myuser  mypwd  > /my/registry2/reg/hub/auth/htpasswd

在 Ubuntu 18.04 或 20.04 上

PS 这里是来自包 apache2-utils 的所有文件......只是一些实用程序而不是任何服务器

dpkg -L apache2-utils
