添加步骤
在alpine中使用ansible需要如下几步
Dockerfile
在Dockerfile中添加上面的语句：
#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/*
使用镜像
拉取镜像
大概103M左右
[root@occluster ~]# docker pull liumiaocn/ansible Using default tag: latest Trying to pull repository docker.io/liumiaocn/ansible ... latest: Pulling from docker.io/liumiaocn/ansible ff3a5c916c92: Already exists 42a81541f983: Pull complete 86602ac17bcb: Pull complete 73cb14e49a3f: Pull complete bdfcad59d746: Pull complete 455ffeaa5bf1: Pull complete dff32643cfa5: Pull complete Digest: sha256:46284f3d3b9e3880f9b65fa6b1fb225b19bc88222badf74aa85936aabc24090f Status: Downloaded newer image for docker.io/liumiaocn/ansible:latest [root@occluster ~]# [root@occluster ~]# docker images |grep ansible docker.io/liumiaocn/ansible latest 8a5cfdf8243f Less than a second ago 103 MB [root@occluster ~]#
使用
进行版本确认
[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] / #
与宿主机(192.168.163.172)进行沟通，事先设定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: Number of key(s) added: 1 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通路确认
/ # ssh 192.168.163.172 hostname occluster / #
ansible动作确认
/ # 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"
}
