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

直到最近这还工作得很好

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 Ubuntu 18.04 和 20.04 上使用 docker

如果您将本地 docker 注册表固定到，它将继续工作

registry:2.7.0

而不是仅使用来获取最新版本 2registry:2可悲的是它已经坏了

详情请参阅https://github.com/docker/distribution-library-image/commit/ab00e8dae12d4515ed259015eab771ec92e92dd4 https://github.com/docker/distribution-library-image/commit/ab00e8dae12d4515ed259015eab771ec92e92dd4（他们删除了 apache2-utils 包）并且https://github.com/GoogleContainerTools/jib/pull/2538/commits/f816c837e34eb389c2cdee1bc9a2918c5d2e33e3 https://github.com/GoogleContainerTools/jib/pull/2538/commits/f816c837e34eb389c2cdee1bc9a2918c5d2e33e3 and https://github.com/GoogleContainerTools/jib/pull/2539 https://github.com/GoogleContainerTools/jib/pull/2539如中所引用的https://github.com/docker/distribution-library-image/issues/106 https://github.com/docker/distribution-library-image/issues/106

或者，您可以使用以下命令安装二进制 htpasswd，而不是从注册表内部执行 htpasswd:2

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 apache2-utils 包的所有文件...只是一些实用程序而不是任何服务器

dpkg -L apache2-utils
