This article is about how to add ansible services to the alpine image. The editor thinks it is very practical, so I share it with you. I hope you can get something after reading this article. Let's take a look at it.

Add step

Using ansible in alpine requires the following steps

Dockerfile

Add the above statement to Dockerfile:

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

Use mirroring

Pull the image

About 103m

Use

Confirm the version

[root@occluster ~] # docker run-it-- name ansible liumiaocn/ansible sh/ # ansible-- versionansible 2.4.1.0 config file = None configured module search path = [default Dec 14 2017, 15:51:29) [GCC 6.4.0] / #

To communicate with the host (192.168.163.172) and set the ssh path in advance, you can use 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)?

Ssh path confirmation

/ # ssh 192.168.163.172 hostnameoccluster/ #

Ansible Action confirmation
