Description Evgheni Dereveanchin 2016-03-15 08:17:53 UTC

Description of problem:
 when running "oc rsh" the TERM environment variable is not set and the shell works in dumb terminal mode. This causes some applications like "less" to work incorrectly which complicates troubleshooting

Version-Release number of selected component (if applicable):
# oc version
oc v3.1.1.6-21-gcd70c35
kubernetes v1.1.0-origin-1107-g4c8e6f4

How reproducible:
Always

Steps to Reproduce:
1. oc rsh <pod>
2. less /path/to/log

Actual results:
 WARNING: terminal is not fully functional

 scrollback does not work

Expected results:
 less works as expected

Comment 3 Jonh Wendell 2016-08-01 12:08:55 UTC

The issue has been fixed in origin

Comment 4 Xingxing Xia 2016-08-02 09:18:49 UTC

Checked in latest Origin 
$ oc/openshift version
openshift v1.3.0-alpha.2+b26dd1e
kubernetes v1.3.0+57fb9ac
etcd 2.3.0+git

And in latest puddle:
$ oc/openshift version
openshift v3.3.0.13
kubernetes v1.3.0+57fb9ac
etcd 2.3.0+git

Both in Origin and OCP, bug is fixed:
$ oc rsh database-1-i91xu
sh-4.2$ echo $TERM
xterm-256color
sh-4.2$ top
sh-4.2$ more /etc/bashrc

Both `top` and `more` work well.

** But `oc exec` does not set TERM **
$ oc exec database-1-i91xu -it -- bash
bash-4.2$ echo $TERM                                                                 
dumb
bash-4.2$ top
TERM environment variable not set.

Comment 5 Andy Goldstein 2016-08-02 10:16:17 UTC

We won't be changing `oc exec` for this
