Question

我有一个安装特定版本的docker的秘诀。我通过属性指定了docker版本。我只是使用该属性。

node.default ['docker'] ['version'] ='1.12.6-1.el7.centos'

配方第一次成功执行，但是当我再次运行它时，它失败了。当我使用default ['docker'] ['version']以外的任何属性（例如node.default ['docker'] ['xyz'] ='1.12.6-1.el7.centos'）时，它在多个收敛上成功执行谁能知道为什么使用default ['docker'] ['version']

时失败

[root@master01 package]# cat _docker.rb
node.default['docker']['version'] = '1.12.6-1.el7.centos'
package "lvm2"
package "device-mapper-persistent-data"

directory "/var/lib/docker"

directory "/etc/docker" do
owner "root"
group "root"
mode "0744"
action :create
recursive true
end

package 'docker-engine' do
version node['docker']['version']
allow_downgrade true
end
service "docker" do
action :enable
end

下面，我使用了属性node.default ['docker'] ['xyz'] ='1.12.6-1.el7.centos'，厨师成功运行了该食谱。

[root@master01 package]# cat _docker.rb
node.default['docker']['xyz'] = '1.12.6-1.el7.centos'
package "lvm2"
package "device-mapper-persistent-data"

directory "/var/lib/docker"

directory "/etc/docker" do
  owner "root"
  group "root"
  mode "0744"
  action :create
  recursive true
end
package 'docker-engine' do
  version node['docker']['xyz']
  allow_downgrade true
end
service "docker" do
  action :enable
end


[root@master01 package]# /opt/chef/bin/chef-apply  _docker.rb

    - install version 1.12.6-1.el7.centos of package docker-engine

使用变量['docker'] ['version']的厨师运行失败，并显示以下错误。

指定的版本在我们的自定义存储库中可用，并且我可以使用yum手动安装该版本。那么谁能知道为什么它会显示这种行为？

厨师版

chef_version=14.2.0
ruby=ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-linux]
program_name=/opt/chef/bin/chef-apply

使用属性default ['docker'] ['version']时，Chef无法安装Docker
