<p>I am familiar with docker in docker (dind) but using along with <code>microsoft/azure-cli</code> image throw <code>docker command not found</code>.</p>

<p>Here is my setup for <code>gitlab-ci.yml</code> file. I have created <code>Service Principal</code> which is used to authenticate to azure cloud and respective resource group. </p>

<pre><code>image: docker:latest

variables:
  PASSWORD: *********
  TENANT_ID: *****-************-*************
  APP_ID: *********-*****-*****
  CLIENT_ID: ****************
  ACR_ID: *******************


stages:
  - build
  - deploy

services:
  - docker:dind

before_script:
  - docker info

build_staging_image:
  stage: build
  image: microsoft/azure-cli
  script:
    - az login --service-principal --username $APP_ID --password $PASSWORD --tenant $TENANT_ID
    - docker build -t azure-vote:latest ./azure-vote
    - docker tag azure-vote votingtestapp.azurecr.io/azure-vote:latest
    - docker push votingtestapp.azurecr.io/azure-vote:latest



deploy:develop:
  stage: deploy
  script:
    - az login --service-principal --username $APP_ID --password $PASSWORD --tenant $TENANT_ID
    - az acr login --name votingTestApp
    - az role assignment create --assignee $CLIENT_ID --role Reader --scope $ACR_ID
    - kubectl apply -f azure-vote-all-in-one-redis.yaml
  only:
    - develop
</code></pre>

<p>Any way to fix this error. I am just trying to create CI/CD pipeline. </p>

<p>The problem is that <code>microsoft/azure-cli</code> docker image does have docker installed and the docker socket is not mounted onto the container. This the <code>docker</code> command will fail.</p>

<p>You are using the <code>microsoft/azure-cli</code> just to login to the registery. But note that you can also login using <code>docker login</code>. Check <a href="https://learn.microsoft.com/en-us/azure/container-registry/container-registry-get-started-docker-cli#log-in-to-a-registry" rel="noreferrer">Log in to a registry</a>.</p>

<p>Therefore, to solve the issue use a <code>dind</code> image and login to azure register using:</p>

<pre><code>docker login myregistry.azurecr.io -u xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx -p myPassword
</code></pre>
