Dear All,
I am new to docker. I have downloaded the centos image and Start the container with the latest image and install httpd
[root@dlp ~]# docker run centos /bin/bash -c “yum -y update; yum -y install httpd”
after that registered the image
[root@dlp ~]#docker commit a0294a053f8c my_image/centos_httpd
d0938f54bfd62c2a108249c1f969aeab80be51fbbaee15b594004d4875327609
Create a container from the registered image and execute which to check httpd
[root@dlp ~]# docker run my_image/centos_httpd /usr/bin/which httpd
get the error
container_linux.go:235: starting container process caused “exec: “/usr/bin/whic h”: stat /usr/bin/which: no such file or directory”
/usr/bin/docker-current: Error response from daemon: oci runtime error: containe r_linux.go:235: starting container process caused “exec: “/usr/bin/which”: sta t /usr/bin/which: no such file or directory”.
[root@ns ~]# docker inspect my_image/centos_httpd
