Metal3 Ironic Container

This repo contains the files needed to build the Ironic images used by Metal3.

Build Status

Description

When updated, builds are automatically triggered on https://quay.io/repository/metal3-io/ironic/

This repo supports the creation of multiple containers needed when provisioning baremetal nodes with Ironic. Eventually there will be separate images for each container, but currently separate containers can share this same image with specific entry points.

The following entry points are provided:

runironic - Starts the ironic-conductor and ironic-api processes to manage the provisioning of baremetal nodes. Details on Ironic can be found at https://docs.openstack.org/ironic/latest/. This is the default entry point used by the Dockerfile.
rundnsmasq - Runs the dnmasq dhcp server to provide addresses and initiate PXE boot of baremetal nodes. This includes a lightweight TFTP server. Details on dnsmasq can be found at http://www.thekelleys.org.uk/dnsmasq/doc.html.
runhttpd - Starts the Apache web server to provide images via http for PXE boot and for deployment of the final images.
runlogwatch - Waits for host provisioning ramdisk logs to appear, prints their contents and deletes files.

All of the containers must share a common mount point or data store. Ironic requires files for both the TFTP server and HTTP server to be stored in the same partition. This common store must include, in <shared store>/html/images, the following images:

ironic-python-agent.kernel
ironic-python-agent.initramfs
final image to be deployed onto node in qcow2 format

The following environment variables can be passed in to customize run-time functionality:

PROVISIONING_MACS - a comma seperated list of mac address of the master nodes (used to determine the PROVISIONING_INTERFACE)
PROVISIONING_INTERFACE - interface to use for ironic, dnsmasq(dhcpd) and httpd (default provisioning, this is calculated if the above PROVISIONING_MACS is provided)
PROVISIONING_IP - the specific IP to use (instead of calculating it based on the PROVISIONING_INTERFACE)
DNSMASQ_EXCEPT_INTERFACE - interfaces to exclude when providing DHCP address (default lo)
HTTP_PORT - port used by http server (default 80)
HTTPD_SERVE_NODE_IMAGES - used by runhttpd script, controls access to the /shared/html/images directory via the default virtual host (HTTP_PORT). (default true)
DHCP_RANGE - dhcp range to use for provisioning (default 172.22.0.10-172.22.0.100)
DHCP_HOSTS - a ; separated list of dhcp-host entries, e.g. known MAC addresses like 00:20:e0:3b:13:af;00:20:e0:3b:14:af (empty by default). For more details on dhcp-host see the man page.
DHCP_IGNORE - a set of tags on hosts that should be ignored and not allocate DHCP leases for, e.g. tag:!known to ignore any unknown hosts (empty by default)
MARIADB_PASSWORD - The database password
OS_<section>_\_<name>=<value> - This format can be used to set arbitary Ironic config options
IRONIC_RAMDISK_SSH_KEY - A public key to allow ssh access to nodes running IPA, takes the format "ssh-rsa AAAAB3....."
IRONIC_KERNEL_PARAMS - This parameter can be used to add additional kernel parameters to nodes running IPA
GATEWAY_IP - gateway IP address to use for ironic dnsmasq(dhcpd)
DNS_IP - DNS IP address to use for ironic dnsmasq(dhcpd)
IRONIC_IPA_COLLECTORS - Use a custom set of collectors to be run on inspection. (default default,logs)
HTTPD_ENABLE_SENDFILE - Whether to activate the EnableSendfile apache directive for httpd (default, false)
IRONIC_CONDUCTOR_HOST - Host name of the current conductor (only makes sense to change for a multinode setup). Defaults to the IP address used for provisioning.
IRONIC_EXTERNAL_IP - Optional external IP if Ironic is not accessible on PROVISIONING_IP.
IRONIC_EXTERNAL_CALLBACK_URL - Override Ironic's external callback URL. Defaults to use IRONIC_EXTERNAL_IP if available.
IRONIC_EXTERNAL_HTTP_URL - Override Ironic's external http URL. Defaults to use IRONIC_EXTERNAL_IP if available.
IRONIC_ENABLE_VLAN_INTERFACES - Which VLAN interfaces to enable on the agent start-up. Can be a list of interfaces or a special value all. Defaults to all.

The ironic configuration can be overridden by various environment variables. The following can serve as an example:

OS_CONDUCTOR__DEPLOY_CALLBACK_TIMEOUT=4800 - timeout (seconds) to wait for a callback from a deploy ramdisk
OS_CONDUCTOR__INSPECT_TIMEOUT=1800 - timeout (seconds) for waiting for node inspection
OS_CONDUCTOR__CLEAN_CALLBACK_TIMEOUT=1800 - timeout (seconds) to wait for a callback from the ramdisk doing the cleaning
OS_PXE__BOOT_RETRY_TIMEOUT=1200 - timeout (seconds) to enable boot retries.

Build Ironic Image from RPMs

The ironic image is built using RPMs for system software and source code for ironic specific software and libraries. It is possible to build it using RPMs from RDO project code setting the INSTALL_TYPE argument to rpm at build time; for example:

podman build -t ironic-image -f Dockerfile --build-arg INSTALL_TYPE=rpm

Custom source for ironic software

When building the ironic image from source, it is also possible to specify a different source for ironic, ironic-lib or the sushy library using the build arguments IRONIC_SOURCE, IRONIC_LIB_SOURCE, and SUSHY_SOURCE. The accepted formats are gerrit refs, like refs/changes/89/860689/2, commit hashes, like a1fe6cb41e6f0a1ed0a43ba5e17745714f206f1f, repo tags or branches, or a local directory that needs to be under the sources/ directory in the container context. An example of a full command installing ironic from a gerrit patch is:

podman build -t ironic-image -f Dockerfile --build-arg INSTALL_TYPE=source \
    --build-arg IRONIC_SOURCE="refs/changes/89/860689/2"

An example using the local directory sources/ironic:

podman build -t ironic-image -f Dockerfile --build-arg INSTALL_TYPE=source \
    --build-arg IRONIC_SOURCE="ironic"

It is also possible to specify an upper-constraints file using the UPPER_CONSTRAINTS_FILE argument. By default this is the upper-constraints.txt file found in the container context; the content of the file can be modified keeping the default name or it's possible to specify an entire different filename as far as it's in the container context.

Apply project patches to the images during build

When building the image, it is possible to specify a patch of one or more upstream projects to apply to the image using the PATCH_LIST argument in the cli command, for example:

podman build -t ironic-image -f Dockerfile --build-arg \
    PATCH_LIST=my-patch-list

The PATCH_LIST argument is a path to a file under the image context. Its format is a simple text file that contains references to upstream patches for the ironic projects. Each line of the file is in the form: project_dir refspec (git_host) where:

project_dir is the last part of the project url including the organization, for example for ironic is openstack/ironic
refspec is the gerrit refspec of the patch we want to test, for example if you want to apply the patch at https://review.opendev.org/c/openstack/ironic/+/800084 the refspec will be refs/changes/84/800084/22 Using multiple refspecs is convenient in case we need to test patches that are connected to each other, either on the same project or on different projects.
git_host (optional) is the git host from which the project will be cloned. If unset, https://opendev.org is used.

	IRONIC_IP="$(ipcalc "${PROVISIONING_IP}" \| grep "^Address:" \| awk '{print $2}')"
	export IRONIC_IP
	until grep -F " ${IRONIC_IP}/" <(ip -br addr show); do
	echo "Waiting for ${IRONIC_IP} to be configured on an interface"
	sleep 1

	echo "Waiting for ${PROVISIONING_INTERFACE} interface to be configured"

	else
	export IPV=4
