使用Cloud-init创建用户

Question

我的虚拟机加载了以下cloud-init脚本：

#cloud-config
# Add groups to the system
# The following example adds the ubuntu group with members foo and bar and
# the group cloud-users.
groups:
  - ugroup

# Add users to the system. Users are added after groups are added.
users:
  - default
  - name: user
    gecos: Testbed as a Service
    primary-group: ugroup
    groups: admin
    passwd: $6$rounds=4096$4pFvtqM5ldfLzR0hE9r7XSOoCO22lN7OB49IopWQ7SQrB5GBTR8X8okMpxXXQZ0jqUOuy4wKY.iYzwQTo7vH6zKx0DqjTFe6jh1

runcmd:
  - [passwd, user, '-u']

但这说明我做错了

由于我得到以下错误：

passwd: user 'user' does not exist
run-parts: /var/lib/cloud/instance/scripts/runcmd exited with return code 1

对我的问题有任何提示或解决方案吗？

我意识到这个问题已经很老了，但是我确实进行了测试以验证它在当前的16.04 Ubuntu映像中是否可以正常工作。

lxd可用于非常快速地创建实例和测试cloud-init配置。 假设您已经设置了lxd，我做了：

$ cat ud.yaml
#cloud-config
# Add groups to the system
# The following example adds the ubuntu group with members foo and bar and
# the group cloud-users.
groups:
  - ugroup

# Add users to the system. Users are added after groups are added.
users:
  - default
  - name: user
    gecos: Testbed as a Service
    primary-group: ugroup
    groups: admin
    passwd: $6$rounds=4096$4pFvtqM5ldfLzR0hE9r7XSOoCO22lN7OB49IopWQ7SQrB5GBTR8X8okMpxXXQZ0jqUOuy4wKY.iYzwQTo7vH6zKx0DqjTFe6jh1

runcmd:
  - [passwd, user, '-u']

$ lxc launch ubuntu-daily:xenial xuser-test \
     "--config=user.user-data=$(cat ud.yaml)"

$ lxc exec xuser-test /bin/bash

# ls -l /home/
total 2
drwxr-xr-x 3 ubuntu ubuntu 6 Jul 18 18:47 ubuntu
drwxr-xr-x 2 user   ugroup 5 Jul 18 18:47 user

# tail -n 2 /etc/group
ugroup:x:1000:
ubuntu:x:1001:

# tail -n 2 /etc/passwd
ubuntu:x:1000:1001:Ubuntu:/home/ubuntu:/bin/bash
user:x:1001:1000:Testbed as a Service:/home/user:

# grep passwd /var/log/cloud-init-output.log
passwd: password expiry information changed.

如果这仍然是您的问题，请针对cloud-init 提交错误 。
