今天小編就為大家分享一篇關(guān)于在alpine鏡像中添加ansible服務(wù)的方法，小編覺得內(nèi)容挺不錯(cuò)的，現(xiàn)在分享給大家，具有很好的參考價(jià)值，需要的朋友一起跟隨小編來看看吧

使用apk add ansible即可在alpine鏡像中添加ansible服務(wù)。

添加步驟

在alpine中使用ansible需要如下幾步

Dockerfile

在Dockerfile中添加上面的語句：

#update apk for install
RUN apk update
#install ansible and openssh
RUN apk add ansible openssh
#init ansible hosts file
RUN mkdir -p /etc/ansible
RUN echo "localhost" >/etc/ansible/hosts
#init rsa ssh key pair
RUN ssh-keygen -t rsa -P "" -f ~/.ssh/id_rsa
#delete cache files 
RUN rm -rf /var/cache/apk/*

使用鏡像

拉取鏡像

大概103M左右

[root@occluster ~]# docker pull liumiaocn/ansible

使用

進(jìn)行版本確認(rèn)

[root@occluster ~]# docker run -it --name ansible liumiaocn/ansible sh
/ # ansible --version
ansible 2.4.1.0
 config file = None
 configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
 ansible python module location = /usr/lib/python2.7/site-packages/ansible
 executable location = /usr/bin/ansible
 python version = 2.7.14 (default, Dec 14 2017, 15:51:29) [GCC 6.4.0]
/ #

與宿主機(jī)(192.168.163.172)進(jìn)行溝通，事先設(shè)定ssh通路，可以使用ssh-copy-id

/ # ssh-copy-id 192.168.163.172
/usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/root/.ssh/id_rsa.pub"
The authenticity of host '192.168.163.172 (192.168.163.172)' can't be established.
ECDSA key fingerprint is SHA256:uh84Xw56LhiCXb1b0uFbX/CoFhkqHGZjtmLwl3qkTOY.
Are you sure you want to continue connecting (yes/no)? yes
/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
expr: warning: '^ERROR: ': using '^' as the first character
of a basic regular expression is not portable; it is ignored
/usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
root@192.168.163.172's password:

Now try logging into the machine, with:  "ssh '192.168.163.172'"
and check to make sure that only the key(s) you wanted were added.
/ #

ssh通路確認(rèn)

/ # ssh 192.168.163.172 hostname
occluster
/ #

ansible動(dòng)作確認(rèn)

/ # echo "192.168.163.172" >>/etc/ansible/hosts
/ # ansible 192.168.163.172 -m ping
192.168.163.172 | SUCCESS => {
  "changed": false, 
  "failed": false, 
  "ping": "pong"
}
/ #
