hey, since this blog post is going onto the website that quote is from, we probably don't need it. Appreciate the messaging, though.
|
|
||
| What did we do? Let's break it down: | ||
|
|
||
| * ``sudo atomic``: We are executing the atomic command with root privledges |
| * ``--system``: And the type of the container we want to install is a system container | ||
| * ``--storage ostree``: We'd like the image to be stored in ostree | ||
| * ``--name etcd``: The name of the container should be etcd | ||
| * ``registry.fedoraproject.org/f26/etcd:latest``: This is the image to use when creating the container |

could you add some notes about --set and how some images, etcd in this case, allow a configuration this way?
It is also possible to see what variables can be customized: atomic info --storage ostree $IMG shows all the supported variables.
With the etcd system container these settings can be overriden anyway by the etcd.conf file, that we now bind mount from the host.

||
| System Containers exist as a way to provide containerized services to a host before traditional container runtimes are ready. System | ||
| Containers do this by utilizing a runc and systemd units and do not deviate from the OCI standards. Let's look at how someone can | ||
| use a system containers to install the ever popular etcd today one Fedora 27 Atomic Host! |

This seems like a lot of terminal text for a blog post. Can we truncate/compress it down to the relevant elements, with ... to indicate the parts we've left out?

@jberkus sounds good. |
would it be better to wait and blast a series of posts around f27 release time? |
|
Isn't release scheduled for the first week of November? |
It got pushed a week. Originally would have been released tomorrow. |
|
Holding this for next week, then, for the release of F27. |
|
Updated per meeting. |
