问题描述
我要在执行命令集后分配一个变量第一个命令是进入openshift pod的外壳.然后整理一个文件，并将其分配给openshift容器外部的变量.
I want to assign a variable after executing the set of commandsThe first command is to get into the shell of the openshift pod. Then cat a file and assign that to a variable outside the openshift container.
我这样尝试过
check=$(oc rsh pod << EOF
cat /var/lib/jenkins/.ssh/check.pub
EOF)
这给我一个错误
bash: warning: here-document at line 41 delimited by end-of-file (wanted `EOF')
推荐答案
我相信第二个EOF本身需要排成一行:
I believe the second EOF needs to be on a line by itself:
check=$(oc rsh pod << EOF
cat /var/lib/jenkins/.ssh/check.pub
EOF
)
