In Oracle Solaris 11.2, several new improvements were added to the Image Packaging System (IPS) to help administrators install software and manage system updates, and also to help developers create and publish software to IPS repositories. You can read about this list of improvements at Tim Foster's blog.

In this article, we will look at the repository mirroring service that was included in Oracle Solaris 11.2 to help administrators keep their local repositories in sync with Oracle's hosted package repositories. We will also look at some of the capabilities that were designed around compliance to ensure that your systems are installed with only the software that you expect them to have.

Creating a Local Package Repository

Oracle hosts a number of package repositories publicly that allow administrators to install and update software directly to systems in their data center. However, in many data center environments there are network restrictions that might require administrators to set up local repositories. By creating a local package repositories, administrators can ensure fast, reliable access to software updates and provide additional mechanisms to constrain the software versions installed on systems (either through package incorporations or freezing) that have gone through internal testing and validation processes to comply with a corporate standard.

In this article, we'll start by first creating a local package repository from the ISO images that are available on the Oracle Technology Network. Let's assume that we have downloaded these images to /mnt. These images contain all the software associated with Oracle Solaris 11.3—both the software that's installed as part of a standard media installation and optional software that's available in the package repository.

root@solaris:~# ls -1 /mnt
README-zipped-repo.txt
install-repo.ksh
sol-11_3-repo_1of5.zip
sol-11_3-repo_2of5.zip
sol-11_3-repo_3of5.zip
sol-11_3-repo_4of5.zip
sol-11_3-repo_5of5.zip
sol-11_3-repo_md5sums.txt

Let's construct a local package repository. We'll first create a ZFS dataset at tank/repositories (assuming there is an additional ZFS pool called tank) in which to host the repository. This means that the repository will exist independently outside the scope of boot environments. We will then run our script (as indicated by the instructions in the README file):

root@solaris:~# zfs create -o mountpoint=/repositories tank/repositories
root@solaris:~# zfs set atime=off tank/repositories
root@solaris:~# zfs set compression=on  tank/repositories
root@solaris:~# zfs get atime,compression tank/repositories
NAME               PROPERTY     VALUE  SOURCE
tank/repositories  atime        off    local
tank/repositories  compression  on     local
root@solaris:~# cd /mnt
root@solaris:/mnt# ./install-repo.ksh -d /repositories
Using sol-11_3-repo download.

Uncompressing sol-11_3-repo_4of5.zip...done.
Uncompressing sol-11_3-repo_5of5.zip...done.
Repository can be found in /repositories.

Let's take a look at the resulting /repositories ZFS dataset:

root@solaris:/mnt# cd
root@solaris:# ls -1 /repositories
COPYRIGHT
NOTICES
README-repo-iso.txt
pkg5.repository
publisher
readme.txt

Now that we have copied over the data, let's change our default IPS publisher to point to this new repository. Note, that we have not enabled the IPS repository depot service that allows clients to connect to this repository over HTTP or HTTPS; for now, we'll just access this repository over the standard file system.

root@solaris:~# pkg set-publisher -G http://pkg.oracle.com/solaris/release -g /repositories/ solaris
root@solaris:~# pkg publisher
PUBLISHER                   TYPE     STATUS P LOCATION
solaris                     origin   online F file:///repositories/

To show that the repository is working correctly, let's install the developer-gnu group package as an example. We will use the presence or absence of these GNU components for verifying that our repository syncing is working. By installing the group package, we will also install all the software needed for a typical GNU developer toolchain.

Now that we have an IPS repository up and running, let's take a ZFS snapshot so we can have a state to revert back to easily.

Manually Mirroring a Package Repository

Administrators can use the pkgrecv command to retrieve packages from one repository to another. In Listing 1 below, we will use the -m latest option to retrieve the latest versions of all packages—as opposed to fetching every package regardless of the versions—as denoted by the * match for the package Fault Management Resource Identifier (FMRI). We will use the Oracle Solaris support repository as the source repository. To do this we're using our My Oracle Support certificates that give us access to this repository. For more details refer to the documentation. Also, we will turn on verbose mode using the -v option.

root@solaris:~# ls
pkg.oracle.com.certificate.pem  pkg.oracle.com.key.pem
root@solaris:~# pkgrecv -s https://pkg.oracle.com/solaris/support -d /repositories -m latest \

Listing 1

In Listing 1, we can see 3751 packages have been refreshed in the repository. This is SRU 32 which has updates across the board also including newer versions of the various GNU tools as part of our commitment keep FOSS updated. 

Let's double-check that we have those versions by looking at the developer/gcc package on our system, and then check the versions that are in our repository, as shown in Listing 2.

In Listing 2, we can see that version 4.8.2-0.175.3.0.0.30.0 is installed, but we have a new version—5.4.0,5.11-0.175.3.22.0.1.0—in the repository as well.

Listing 3

In Listing 3, we can see that we've installed the latest GNU packages, including the gcc compiler. pkgrecv works great to refresh our local package repository. A new boot environment called solaris-1 was created. And the system was rebooted to move to this new boot environment.

pkgrecv also takes another option --clone to produce an exact clone of a repository (including all time stamps). If you are copying a repository from scratch, it is recommended to use the --clone option because it result in a faster operation.

Using pkgrecv is a pretty manual process. We could easily create a cron job to do this for us, but instead we will use the new mirroring service feature included since Oracle Solaris 11.2. Using this feature provides a few more benefits that just using cron alone, for example, integration into the Oracle Solaris Service Management Facility (SMF), logging, publisher configuration management, and more.

Before we look at the new IPS package mirroring service, let's roll back our local package repository to the original state and revert the changes we made when we installed the GNU developer packages, as shown in Listing 4. First we roll back to the original boot environment by activating it and then rebooting, then we roll back the zfs snapshot on the other zpool. And finally we'll use the command—pkg exact-install—to install and update our system as if we were installing onto a bare system. This command is especially useful for administrators trying to enforce compliance, for example, to ensure that a validated configuration is used and that no additional unnecessary packages are installed on a system.

This particular system was installed using the Oracle Solaris 11.3 Interactive Text Installer, which uses the solaris-large-server group package as the boundary in which to install a basic server profile. We will use this as the boundary that we want to revert to. Because in this case we've already moved back and rebooted to the older boot environment, performing this exact installation not will cause a new boot environment, and only packages will be removed. No additional reboot is necessary.

Listing 4

In Listing 4, we can see that 100 packages were removed from the system, let's check the status of our system and repository for our GNU Developer packages.

Automatic Mirroring with the IPS Repository Mirroring Service

The IPS package mirroring service, application/pkg/mirror, helps to automate the process of updating package repositories with content from another package repository. As before, we'll update our package repository located at /repositories with the updated content in the Oracle Solaris 11.3 support repository. Note, this will take a very long time and quite some space as the support repository is pretty large by now. This service is managed using SMF and is initially disabled, as shown below:

root@solaris:~# svcs pkg/mirror
STATE          STIME    FMRI
disabled       23:23:17 svc:/application/pkg/mirror:default

We will use the standard SMF administrative commands to make the changes that we need to make to the configuration. Let's first check the default configuration of this service instance using the svccfg command, as shown in Listing 5:

root@solaris:~# svccfg -s pkg/mirror:default
svc:/application/pkg/mirror:default> listprop config
config                      application        
config/cache_dir           astring     /var/cache/pkg/mirror
config/crontab_period      astring     "30 2 random * *"
config/debug               boolean     false
config/publishers          astring     solaris
config/ref_image           astring     /
config/repository          astring     /var/share/pkg/repositories/solaris
config/stability           astring     Evolving
config/value_authorization astring     solaris.smf.manage.pkg-mirror

Listing 5

Right away, we can see in Listing 5 that we'll want to change the config/repository property to point to /repositories instead, and depending on when we want to have this service pull updates, we might want to change the config/crontab_period property as well.

For this article, we will pull updates every five minutes so we can see that it is working, but the recommendation would be to pull updates during periods of relative inactivity within the data center, for example, outside of business hours.

svc:/application/pkg/mirror:default> setprop config/repository = astring: "/repositories"
svc:/application/pkg/mirror:default> setprop config/crontab_period = astring: "0,5,10,15,20,25,30,35,40,45,50,55 * * * *"
svc:/application/pkg/mirror:default> listprop config
config                      application        
config/cache_dir           astring     /var/cache/pkg/mirror
config/debug               boolean     false
config/publishers          astring     solaris
config/ref_image           astring     /
config/stability           astring     Evolving
config/value_authorization astring     solaris.smf.manage.pkg-mirror
config/repository          astring     /repositories
config/crontab_period      astring     "0,5,10,15,20,25,30,35,40,45,50,55 * * * *"
svc:/application/pkg/mirror:default> refresh
svc:/application/pkg/mirror:default> exit

By default, the service uses the publisher configuration on the system as the source repositories to mirror. This is configured using the config/ref_image SMF repository (as indicated by the value of /). This means that it will try to pull from file:///repositories/, since that is what is configured as our default publisher.

We have two options. We can either change our publisher back to the Oracle-hosted publisher, or we can create a new image using pkg image-create to provide our correct publisher information and then supply this as the reference image for the mirror service. Let's choose the first option for now (the other example is covered in the product documentation).

We will also need to change the user and group ownership of /repositories, since the mirror service runs as the pkg5srv user; this is a problem only when mirroring to existing repositories.

root@solaris:~# ls
pkg.oracle.com.certificate.pem  pkg.oracle.com.key.pem
root@solaris:~# pkg set-publisher -k pkg.oracle.com.key.pem -c pkg.oracle.com.certificate.pem \ 
-G /repositories -g https://pkg.oracle.com/solaris/support solaris
root@solaris:~# pkg publisher PUBLISHER TYPE STATUS P LOCATION solaris origin online F https://pkg.oracle.com/solaris/support/ root@solaris:~# chown -R pkg5srv:pkg5srv /repositories

Now that we have completed the configuration, let's enable this service instance using the svcadm enable command and then check that it's online using svcs.

root@solaris:~# svcadm enable pkg/mirror:default
root@solaris:~# svcs pkg/mirror:default
STATE          STIME    FMRI
online         23:38:00 svc:/application/pkg/mirror:default

The service logs activity to the /var/log/pkg/mirror/ location. We can check to see that this service is working correctly by checking a few different logs:

root@solaris:# tail -f /var/log/pkg/mirror/mirror.default.log
20180603T234001Z: svc:/application/pkg/mirror:default updates to /repositories from 
https://pkg.oracle.com/solaris/support/ : ^C root@solaris:/var/log/pkg/mirror# tail -f /var/log/pkg/mirror/mirror.default.log.tmp Processing packages for publisher solaris ...

After many hours (the Oracle Solaris 11 support repository is huge!), the mirroring service will have been completed, and we can check the status of our repository for packages that we'd expect to be in our refreshed repository.

root@solaris:~# pkgrepo -s /repositories/ list developer/gcc

We can even look at what versions of entire are included in our repository (entire is a package incorporation that represents the release boundaries of Oracle Solaris 11):

root@solaris:~# pkgrepo -s /repositories/ list entire
PUBLISHER NAME                                          O VERSION

...

solaris   entire                                          0.5.11,5.11-0.151.0.1.2:20110127T225841Z

solaris   entire                                          0.5.11,5.11-0.151.0.1.1:20101222T214417Z

It works!

A final remark is on storage usage for this and the need to plan for this. There are two locations that potentially will require a lot of space. The first is expected, the location of the repository, which in this case is /repositories. The second is /var/cache/pkg/mirror/default, this will fill while the mirror service is being used to fill the repository. In this case because we used mirror to fill the full repository it is also very large. to work around this in this case a symbolic link was created to a directory to the /tank pool which has plenty of space.

The full repository now is 138GB, and also note that the total on /tank is 278GB. This is in part because of the symbolic link that was created. So plan to have enough storage space.

Conclusion

The IPS mirroring service is a very useful way of mirroring repositories, both Oracle-hosted repositories and local repositories. Using multiple SMF instances of the application/pkg/mirror service, administrators can quickly sync different repositories to allow better geographical distribution of repositories serving different clients across a global data center environment.
