openshift - 无法在 openshift v3 上运行“oc rsh POD mysqldump foo”

Question

我已经在我的 linux 电脑上安装了 oc 并登录了 openshift。当我跑步时

oc rsh mysql-55-centos7-1-1aa3 ls -al /tmp/
total 72428
drwxrwxrwt. 1 root       root       35 Oct 30 00:38 .
drwxr-xr-x. 1 root       root       39 Oct 23 23:53 ..
drwxrwxrwt. 2 root       root        6 Nov  2  2016 .ICE-unix
drwxrwxrwt. 2 root       root        6 Nov  2  2016 .Test-unix
drwxrwxrwt. 2 root       root        6 Nov  2  2016 .X11-unix
drwxrwxrwt. 2 root       root        6 Nov  2  2016 .XIM-unix
drwxrwxrwt. 2 root       root        6 Nov  2  2016 .font-unix
-rwx------. 1 root       root      827 Nov  2  2016 ks-script-la2kM
-rwxr-xr-x. 1 1063070000 root  3343400 Oct 24 04:08 mysql

它有效，但是

oc rsh mysql-55-centos7-1-1aa3 mysqldump -h1.1.1.1 -uuser -ppassword data1 > /tmp/data1.sql

command terminated with exit code 126

它不起作用

oc rsh mysql-55-centos7-1-1aa3 mysqldump

rpc error: code = 13 desc = invalid header field value "oci runtime error: exec failed: container_linux.go:247: starting container process caused \"exec: \\\"mysqldump\\\": executable file not found in $PATH\"\n"

command terminated with exit code 126

如何解决问题？

Answer 1

我对 postgres 有同样的问题。

我得到了它的工作：

oc rsh MY_POD /bin/sh -i -c 'pg_dump'

scl_enable以这种方式激活。( /bin/sh -i -c ...)
