Error enabling service with apache2 in chef/centos-7

[mlamy]

Hi,

I'm trying to build an apache2 container with centos7 image. I started with init: knife container docker init siag/apache2 -r 'recipe[apache2]' -f chef/centos-7 -b

After that I changed first-boot.json to:

{ "run_list": [ "recipe[apache2]" ], "container_service": { "apache2": { "command": "/usr/sbin/httpd -k start" } } }

And finally I tried to build the container with: knife container docker build siag/apache2 -b

Unfortunately I can't figure out why is not working. Can someone please help me understand why the service can't be enabled ?

Thank you,

Miguel

Check out https://github.com/opscode/knife-container/issues/44 for the solution.

Hi Tom. Thank you for you quick reply. I missed #44 completely...sorry.

I changed first-boot.json to:

{ "run_list": [ "recipe[apache2]" ], "container_service": { "httpd": { "command": "/usr/sbin/httpd -DFOREGROUND" } } }

Unfortunately with that name change I don't see runit change service line - Provider for service[apache2] has been replaced with Chef::Provider::ContainerService::Runit in log:

And I get:

Chef::Exceptions::Service

service[apache2]: unable to locate the init.d script!

service("apache2") do action [:enable, :start] supports {:restart=>true, :reload=>true, :status=>true, :start=>true} retries 0 retry_delay 2 guard_interpreter :default service_name "httpd" pattern "apache2" reload_command "/sbin/service httpd graceful" cookbook_name "apache2" recipe_name "default" only_if "/usr/sbin/httpd -t" end

Instead of

service("apache2") do provider Chef::Provider::ContainerService::Runit action [:enable, :start] supports {:restart=>true, :reload=>true, :status=>true, :start=>true} retries 0 retry_delay 2 guard_interpreter :default service_name "httpd" pattern "apache2" reload_command "/usr/sbin/service httpd graceful" cookbook_name "apache2" recipe_name "default" end

am I still missing something ?

Thanks for your patience. Miguel

not that I can see. After you changed the first-boot.json, what command did you run?

[tduffield]

Also, it would be very helpful if you could provide the full output of your command in a formatted way (via a gist or pastebin).

Hi Tom. The full log is at: https://gist.github.com/mlamy/7e0857139acc6773978d.

My knife-container version is 0.2.4.

I executed: knife container docker init siag/apache2 -r 'recipe[apache2]' -f chef/centos-7 -b --force and after that I changed first-boot.json and executed knife container docker build siag/apache2 -b --force

I tried wih centos-6 and it worked :-) . I'm guessing that this problem may be related how centos 7 start services. It uses systemctl and not /etc/init.d as before. If my guessing is correct can you suggest an workaround for this problem ?

Thank you. Miguel
