docker_lxcОфициальный docker-образ от Microsoft содержал Azure CLI версии 0.9.8, а требовалась 0.10.

Пример сборки и отправки в Docker Hub образа с azure-cli 0.10.2.

Содержимое Dockerfile:

FROM ubuntu:14.04
RUN apt-get update && apt-get install -y \
    node.js npm \
    && ln -s /usr/bin/nodejs /usr/bin/node \
    && npm install azure-cli -g

Собираем:

$ sudo docker build -t setevoy/azure-cli .

Можно поискать аналогичные образы:

$ sudo docker search azure-cli

И добавить свой:

$ sudo docker push setevoy/azure-cli
The push refers to a repository [setevoy/azure-cli] (len: 1)
47058f28a32c: Image already exists 
f8bd1e6f7e58: Image successfully pushed 
62059538b3f4: Image successfully pushed 
20fc819717cc: Image successfully pushed 
2334d959c0cf: Image successfully pushed

Если после Ctrl+C будет ошибка вида:

FATA[0000] Error response from daemon: push setevoy/azure-cli is already in progress

Перезапустите Docker (правда потом вероятна ошибка “Image already exists“):

$ sudo service docker restart
docker stop/waiting
docker start/running, process 12074

Проверяем:

$ sudo docker search azure-cli | grep setevoy
setevoy/azure-cli                    Azure-CLI (Node), Ubuntu 14.04                  0

И запускаем:

$ sudo docker run -ti setevoy/azure-cli
root@e5a5a8f1304d:/# azure --version
0.10.2 (node: 0.10.25)

Готово.
