title: Docker command not found in local Jenkins multi branch pipeline
body: <p>I have <strong>BookStore</strong> Spring Boot project that needs to be deployed through Jenkins. Docker installed in my local machine (macOS) and Jenkinsfile created as follows</p>
  
  <pre><code>pipeline

  <p>I created multi-branch pipeline in Jenkins and when I try to run it, I got following error</p>
  
  <pre><code>/Users/Shared/Jenkins/Home/workspace/BookStore_master-VPWQ32ZZPV7CVOXNI4XOB3VSGH56MTF3W34KXKZFJKOBMSGLRZQQ@tmp/durable-70dd5a81/script.sh: line 2: docker: command not found
  
  script returned exit code 127

  <p>This looks strange to me as docker available in local machine, and also configured <strong>Global Tool Configuration</strong> section with appropriate details as shown below. I looked into several posts and none of the solutions worked so far.</p>
