In this blog post, I’m going to practice publishing and promoting content views using the hammer CLI. I already know how to do this using the Satellite/Foreman web UI. First, I’m going to create the Base content view for Operations organization and Boston location. [root@foreman ~]# hammer content-view create \ > --name Base --organization Operations \ > --description 'Base Packages' Content view created.

[root@foreman ~]# hammer lifecycle-environment list --organization Operations ---|---------|------ ID | NAME | PRIOR ---|---------|------ 6 | Library | ---|---------|------ When we create our first environment, we’ll need to use the ID of the Library, which is 6 in this case....

Let’s learn how to create an organization and location on Foreman/Satellite server using the hammer command-line-interface. In this example, I’m going to create an organization called: Operation and assign its location to Boston. On the Foreman server, excute the following commands: [root@foreman ~]# hammer organization create --name Operations Organization created. [root@foreman ~]# hammer location create --name Boston Location created. [root@foreman ~]# hammer organization add-location --name Operations \ > --location Boston The location has been associated....

When I setup Foreman (Satellite) server, I didn’t have Ansible support enabled. Here is how it can be done later on. If we only need Ansible support, it’s sufficient to just run this command: # foreman-installer \ --enable-foreman-plugin-ansible \ --enable-foreman-proxy-plugin-ansible Just a note for myself, I also need Remote Execution enabled if I want to run Ansible playbooks as Job Templates. # foreman-installer \ --enable-foreman-plugin-remote-execution \ --enable-foreman-proxy-plugin-remote-execution-ssh Note that the remote execution feature is enabled by default on Foreman/Satellite server....

One of my Red Hat servers is behind proxy with no access to the outside world. This box is registered to a Satellite server to receive software updates. I want to install Zabbix server on this server using the packages from Zabbix upstream directly. To do this, I need to set the proxy for the Zabbix’s repository. There are a few ways to do this. For my purpose, the best place is to set proxy=proxy_server directly in the ....
