String docker容器-ssh adduser passwd

我已经构建了一个脚本“createcontainer.sh”来自动创建一个容器。我对脚本的调用如下：

./createdocker.sh newuser newpass

在脚本内部，这两个参数被分配给变量，如下所示：

USERNAME=$1     <-- thus USERNAME=newuser
PASSWORD=$2     <-- thus PASSWORD=newpass

SCRIPT="adduser $USERNAME;\                                    <-- add newuser
echo -e $PASSWORD\n$PASSWORD | (passwd --stdin $USERNAME);\    <-- set newpass
echo ssh username: $USERNAME;\
echo ssh password: $PASSWORD;\
echo Instance Login Success;\
exit"

[root@netunique docker-sshd]# ./signup_createdocker.sh newuser newpass
Instance Created
adduser newuser;echo -e newpass\nnewpass | (passwd --stdin newuser);echo ssh username: newuser;echo ssh password: newpass;echo Instance Login Success;exit
Warning: Permanently added '[localhost]:32936' (RSA) to the list of known hosts.
Changing password for user newuser.
passwd: all authentication tokens updated successfully.    <-- appears 'set newpass' worked
ssh username: newuser
ssh password: newpass
Instance Login Success

这将告诉“createcontainer.sh”脚本使用root和$ORIGINALPASSWORD登录$PORT上容器的$IP，自动接受SSH主机密钥，然后执行$script，其定义如下：

USERNAME=$1     <-- thus USERNAME=newuser
PASSWORD=$2     <-- thus PASSWORD=newpass

SCRIPT="adduser $USERNAME;\                                    <-- add newuser
echo -e $PASSWORD\n$PASSWORD | (passwd --stdin $USERNAME);\    <-- set newpass
echo ssh username: $USERNAME;\
echo ssh password: $PASSWORD;\
echo Instance Login Success;\
exit"

[root@netunique docker-sshd]# ./signup_createdocker.sh newuser newpass
Instance Created
adduser newuser;echo -e newpass\nnewpass | (passwd --stdin newuser);echo ssh username: newuser;echo ssh password: newpass;echo Instance Login Success;exit
Warning: Permanently added '[localhost]:32936' (RSA) to the list of known hosts.
Changing password for user newuser.
passwd: all authentication tokens updated successfully.    <-- appears 'set newpass' worked
ssh username: newuser
ssh password: newpass
Instance Login Success

请注意，上面的newpass\nnewpass用引号（“）括起来，而在脚本中，整个字符串用引号（“）括起来，特别是echo-e语句。如果有人能建议如何解决这个问题，这将对我有很大帮助。提前感谢您的帮助。

之前

SCRIPT="adduser $USERNAME;\                                    <-- add newuser
echo -e $PASSWORD\n$PASSWORD | (passwd --stdin $USERNAME);\    <-- set newpass
echo ssh username: $USERNAME;\
echo ssh password: $PASSWORD;\
echo Instance Login Success;\
exit"

我必须在$PASSWORD\n$PASSWORD（我以前尝试过）周围加上引号（“），但我还必须用黑色斜杠（\）来避免它们，如下图所示：\”

SCRIPT="adduser $USERNAME;\
echo -e \"$PASSWORD\n$PASSWORD\" | (passwd --stdin $USERNAME);\
echo ssh username: $USERNAME;\
echo ssh password: $PASSWORD;\
echo Instance Login Success;\
exit"
