AWS opsworks上的Chef 12脚本无法安装jenkins

Question

I have the following chef 12 script which I am running on aws opsworks to install jenkins. I sourced it from the following site: https://wiki.jenkins-ci.org/display/JENKINS/Installing+Jenkins+on+Ubuntu When I run it, it fails with the following error:

execute 'add jenkins source to apt' do
    command "wget -q -O - https://pkg.jenkins.io/debian/jenkins-ci.org.key | sudo apt-key add -"
end


file '/etc/apt/sources.list.d/jenkins.list' do
    content 'deb http://pkg.jenkins.io/debian-stable binary/'
end

execute 'update apt-get' do
    command 'apt-get update'
end


package 'install Jenkins' do
    package_name "jenkins"
end

package 'install nginx' do
    package_name 'nginx'
end

file '/etc/nginx/sites-enabled/default' do
    action :delete
end

cookbook_file '/etc/nginx/sites-available/jenkins' do
    source 'jenkins'
end

link '/etc/nginx/sites-enabled/jenkins' do
    to '/etc/nginx/sites-available/jenkins'
    link_type :symbolic
end

service 'nginx' do
    action :restart
end

service 'jenkins' do
    action :restart
end

When I run execute recipes on a c4.4xlarge image running ubuntu 14.04, I get the following errors

Setting up jenkins (2.32.1) ...
* Starting Jenkins Continuous Integration Server jenkins
...fail!
Setting up libnss3-nssdb (2:3.26.2-0ubuntu0.14.04.3) ...

and

I am not sure why jenkins is failing to start. When I run the recipe twice on the same instance it succeeds the second time. Any help is much appreciated, as this is my first Chef script.

Answer 1

It turns out the answer was in the chef stacktrace file. The apt-get process runs twice and could not access the lockfile in dpkg in the install package step. Changing

execute 'update apt-get' do
    command 'apt-get update'
end


package 'install Jenkins' do
    package_name "jenkins"
end

to

apt_update 'all platforms' do
    action :update
end

apt_package 'jenkins' do
  action :install
end

solved the issue.
