To +tell Packer to use a proxy set the HTTP_PROXY environment variable to your proxy +server. Alternatively you may redefine iso_url to a local file. + +To use a proxy during the installation define the `KS_PROXY` variable in the +environment, as bellow: + +```shell +export KS_PROXY="--proxy=\"${HTTP_PROXY}\"" +``` + +## Building an image + +You can easily build the image using the Makefile: + +```shell +make +``` + +Alternatively you can manually run packer. Your current working directory must +be in packer-maas/centos9-stream, where this file is located. Once in +packer-maas/centos9-stream you can generate an image with: + +```shell +packer init +PACKER_LOG=1 packer build . +``` + +Note: centos9-stream.pkr.hcl is configured to run Packer in headless mode. Only Packer +output will be seen. If you wish to see the installation output connect to the +VNC port given in the Packer output or change the value of headless to false in +centos9-stream.pkr.hcl. + +Installation is non-interactive. + +## Uploading an image to MAAS + +```shell +maas $PROFILE boot-resources create \ + name='custom/9-stream-custom' title='CentOS 9 Stream Custom' \ + architecture='amd64/generic' filetype='tgz' base_image='rhel/9' \ + content@=centos9-stream.tar.gz +``` + +## Default Username + +The default username is ```cloud-user``` diff --git a/centos9-stream/centos9-stream.pkr.hcl b/centos9-stream/centos9-stream.pkr.hcl new file mode 100644 index 00000000..ce1e940e --- /dev/null +++ b/centos9-stream/centos9-stream.pkr.hcl @@ -0,0 +1,48 @@ +packer { + required_version = ">= 1.7.0" + required_plugins { + qemu = { + version = "~> 1.0" + source = "github.com/hashicorp/qemu" + } + } +} + +variable "filename" { + type = string + default = "centos9-stream.tar.gz" + description = "The filename of the tarball to produce" +} + +variable "centos9_stream_iso_url" { + type = string + default = "https://mirror.stream.centos.org/9-stream/BaseOS/x86_64/iso/CentOS-Stream-9-latest-x86_64-boot.iso" +} + +source "qemu" "centos9-stream" { + boot_command = [" ", "inst.ks=http://{{ .HTTPIP }}:{{ .HTTPPort }}/centos9-stream.ks ", "console=ttyS0 inst.cmdline", ""] + boot_wait = "3s" + communicator = "none" + disk_size = "4G" + headless = true + http_directory = "http" + iso_checksum = "none" + iso_url = var.centos9_stream_iso_url + memory = 2048 + qemuargs = [["-serial", "stdio"], ["-cpu", "host"]] + shutdown_timeout = "1h" +} + +build { + sources = ["source.qemu.centos9-stream"] + + post-processor "shell-local" { + inline = [ + "SOURCE=centos9-stream", + "OUTPUT=${var.filename}", + "source ../scripts/fuse-nbd", + "source ../scripts/fuse-tar-root" + ] + inline_shebang = "/bin/bash -e" + } +} diff --git a/centos9-stream/http/centos9-stream.ks.in b/centos9-stream/http/centos9-stream.ks.in new file mode 100644 index 00000000..b21042fe --- /dev/null +++ b/centos9-stream/http/centos9-stream.ks.in @@ -0,0 +1,72 @@ +url --mirrorlist=https://mirrors.centos.org/metalink?repo=centos-baseos-9-stream&arch=x86_64&protocol=https,http ${KS_PROXY} +poweroff +firewall --enabled --service=ssh +firstboot --disable +ignoredisk --only-use=vda +lang en_US.UTF-8 +keyboard us +network --device eth0 --bootproto=dhcp +firewall --enabled --service=ssh +selinux --enforcing +timezone UTC --isUtc +bootloader --location=mbr --driveorder="vda" --timeout=1 +rootpw --plaintext password + +repo --name=baseos --metalink=https://mirrors.centos.org/metalink?repo=centos-baseos-9-stream&arch=x86_64&protocol=https,http ${KS_PROXY} +repo --name=appstream --metalink=https://mirrors.centos.org/metalink?repo=centos-appstream-9-stream&arch=x86_64&protocol=https,http ${KS_PROXY} +repo --name=centos --metalink=https://mirrors.centos.org/metalink?repo=centos-crb-9-stream&arch=x86_64&protocol=https,http ${KS_PROXY} + +zerombr +clearpart --all --initlabel +part / --size=1 --grow --asprimary --fstype=ext4 + +%post --erroronfail +# workaround anaconda requirements and clear root password +passwd -d root +passwd -l root + +# Clean up install config not applicable to deployed environments. +for f in resolv.conf fstab; do + rm -f /etc/$f + touch /etc/$f + chown root:root /etc/$f + chmod 644 /etc/$f +done + +rm -f /etc/sysconfig/network-scripts/ifcfg-[^lo]* + +# Kickstart copies install boot options.
