I made the README file as a way to track changes I'd make to the installer over the last few years. I'd considered automating it, but never really had a need, so thank you for doing that. I added comments to a recent review adding lz4 to the installer, identifying pkgs that should be dropped, but haven't really looked through the make-installer-images.sh script yet. One reason I just did it manually was to ensure everything went smoothly, so I could catch any oddities along the way. There'd need to be a lot of error checking, to ensure the installer is updated safely. The idea of using a symlink is good. I'd suggest we include it in the stx/downloads dir. It could be created by the populate_downloads.sh script as an additional step, maybe with an environment variable or argument to point to a particular location, so there's no change in developer process (aside from maybe setting a new var) -----Original Message----- From: Hu, Yong [mailto:yong.hu@intel.com] Sent: Monday, September 17, 2018 9:07 PM To: Penney, Don; Cordoba Malibran, Erich; starlingx-discuss@lists.starlingx.io Subject: Re: [Starlingx-discuss] Build installer instructions Originally here is a readme to describe how to make/update installer images: cgcs-root/stx/stx-metal/installer/initrd/README Later I made 2 scripts to automate the process descripted in that readme: cgcs-root/build-tools/update-pxe-network-installer cgcs-root/build-tools/make-installer-images.sh While, due to the hard-coding (referring to the mirror folder for a specified version, for example, /import/mirrors/CentOS/tis-installer/initrd.img-stx-0.4) in "~/cgcs-root/stx/stx-metal/installer/pxe-network-installer/centos/build_srpm.data", we have to manually edit this file every time. So, I would agree Don's suggest that we use the symlinks to the latest version to get rid of versions attached. Further, instead of using the hard-coded "/import/mirror/CentOS/tis-installer", we can use a relative directory, something like "~/cgcs-root/cgcs-centos-repo/tis-installer". Here "tis-installer" could be a symbol link to the actual place where the init images are placed.

So presumably, this would not be part of a general designer workflow. Historically, we upversioned these images whenever they were updated, but this introduces some challenges under Starling-X. It may make sense to drop the version number from the images as referenced in the pxe-network-installer package build, essentially treating it as a .latest version. Individuals or groups could then manage their own installer version history as they see fit, ie. build images with 0.1, 0.2, 0.3, with symlinks to the latest perhaps. If these images aren't being hosted somewhere, if individuals/groups are generating their own, then the versioning shouldn't be in the build files. -----Original Message----- From: Cordoba Malibran, Erich [mailto:erich.cordoba.malibran@intel.com] Sent: Monday, September 17, 2018 12:12 PM To: starlingx-discuss@lists.starlingx.io Subject: [Starlingx-discuss] Build installer instructions Hi, I would like to share/discuss the instructions to generate the installer before are publish into the wiki. I couldn't find a previous version of these instructions, probably I confused with this warning from the download_mirror.sh[0]. The update-pxe-network-installer script follows the steps detailed here[1]. Build installer =============== To get your StarlingX ISO ready to use, you will need to create the init files that will be used to boot the ISO as well to boot additional controllers and compute nodes. Once you had run `build-iso`, run: ``` build-pkgs --installer ``` This will build `rpm` and `anaconda` packages. Then run: ``` update-pxe-network-installer ``` The update-pxe-network-installer` covers the steps detailed in `$MY_REPO/stx/stx-metal/installer/initrd/README`. This script will create three files on `/localdisk/loadbuild/<user>/<project>/pxe- network-installer/output` ``` new-initrd.img new-squashfs.img new-vmlinuz ``` Then, rename them to: ``` initrd.img-stx-0.2 squashfs.img-stx-0.2 vmlinuz-stx-0.2 ``` There are two ways to use these files: 1. Store the files in the '/import/mirror/CentOS/tis-installer/` folder for future use. 2. Store it in an arbitrary location and modify the `$MY_REPO/stx/stx- metal/installer/pxe-network-installer/centos/build_srpm.data` file to point to these files. Now, the `pxe-network-installer` package needs to be recreated and the ISO regenerated. ``` build-pkgs --clean pxe-network-installer build-pkgs pxe-network-installer build-iso ``` Now your ISO should be able to boot. Updating these files is not a common tasks, it is recommended only do it if the kernel version is upgraded or new kernel modules are added. ===================== End of documentation [0] http://git.starlingx.io/cgit/stx-tools/tree/centos-mirror-tools/download_mir...
