I was trying to tweak Core linux to boot in uefi mode, but it's only working in legacy mode and i don't really know how to start with it, i tried copying efi from ubuntu server install but i just booted to uefi shell.

When installing the system with [coreos-installer](https://coreos.github.io/coreos-installer/) utility, **if the image contains an embedded Ignition configuration**, after the installation completes, the system will reboot. **Question**: Is there a way to override this behaviour to shutdown instead of rebooting? For example via kernel arguments or something similar? **Why**: The reason I want this behaviour is that I'm installing Fedora CoreOS via a live ISO on VirtualBox, and I have the Ignition configuration embedded into the ISO. Since the installation starts automatically, I don't have to input commands and shutdown manually. However, once the installation process completes, the system _reboots_, starting the live environment again and re-installing the system in a loop, until I manually stop the VM and "remove" the live ISO media. So I have to intercept when the installation is done, which is a little inconvenient.

## Problem Context: Fedora CoreOS operating system (read-only root filesystem). I'm trying to add myuser to group dialout so I can access /dev/ttyS1 via its group owner. However, during first boot, Ignition phase keeps failing. **Questions**: - How can I add a custom user to group dialout? - How is it possible that it fails with the 2 error messages below ("group doesn't exist" and "group already exists")? Docs reference: [Fedora CoreOS Docs | Configuring Groups](https://docs.fedoraproject.org/en-US/fedora-coreos/authentication/#_configuring_groups) ## What I tried ### Adding User to Group It fails with message _**"useradd: group 'dialout' does not exist\n"**_.

On a relatively fresh and simple CoreOS system, trying to run the following command: podman run --rm docker.io/curlimages/curl -v host.containers.internal:2040 Results in the following error: {"msg":"exec container process /entrypoint.sh: Permission denied","level":"error","time":"2024-11-22T22:12:56.046889Z"} To which I am at a complete loss. I've tried the following: - sudo setenforce 0 to disable SELinux temporarily, which did not change the error received. - Added the --userns=keep-id flag to the command, which also didn't change the results. EG: podman run --userns=keep-id --rm docker.io/curlimages/curl -v host.containers.internal:2040 - For other more complex podman containers, I tried setting the :z flag for volume mounts to no avail. There must be something I'm doing wrong on my system. The only abnormal part of my system is that I have podman and docker both installed on the same machine for compatibility reasons but my understanding is that this shouldn't be a conflict.

I am installing a Fedora CoreOS v39.2024030 on a bare metal system (PowerEdge server) through a iDRac interface. It's a two-step process: 1. Here it's needed to boot the system into a LiveISO (virtual cd-rom) and perform the install step:

coreos-installer install /dev/sda --ignition-url http://filepath.ign 

Once file system is copied, it reboots to perform the installation. 2. Reboot and perform automated installation based on ignition file instructions. My issue is that when I first boot the system with liveCD, it shows my two disks (block storage names) **sda and sdb**, but when the system reboots for the second phase, those disk names change to **sdb and sdc**. The reason is that step 1 creates some temporary disk of 0B which sits at sda. Because of this, the setup fails with the error "Problem opening /dev/sda". How can I make sure the disk label does not change on reboot? References: Official Documentation

My homelab environment is primarily git repo->puppet apply->centos7 hardware running kvm or guests. Simple tooling but it works. I'm doing a lot more terraform at work these days and have been thinking about refreshing my homelab with an ansible/terraform pattern but I've been looking at my OS base for the KVM hosts and wondering if there is a better way. So, the question...... Is anyone aware of a unix OS pattern that's PXE booting, immutable, container friendly and usable as a basic KVM host? Something like CoreOS/Flatcar but for KVM guests instead of just containers. Ideally with config data from cloud-init and something like vault. Thanks!

I'm trying to install Fedora CoreOS using virt-install, as described here: https://docs.fedoraproject.org/en-US/fedora-coreos/getting-started/ The exact command I'm running:

I'm running this command as root. The ignition file is working as I've successfully used it to deploy this VM from an iso file.

## TL;DR Is "Container Linux", "Red Hat CoreOS" and "Fedora CoreOS" basically the same? What are the differences in between? --- ## TS; DR I understood that "CoreOS" was renamed to "Container Linux by CoreOS". And then "Container Linux" and CoreOS' developers were acquired by Red Hat . But I'm confused between "Container Linux", "Red Hat CoreOS" and "Fedora CoreOS". First, they announced that "Container Linux" will be reborn as "Red Hat CoreOS" , which I thought the name will be "Red Hat CoreOS". But, then, they announced to launch "Fedora CoreOS" and they intend to maintain Container Linux at least into 2020. So, currently, there are 3 types of "CoreOS" I think. The original "Container Linux", and "RedHat CoreOS" and "Fedora CoreOS". I don't understand well what the ECO system of Red Hat they say are. Is "Use it free with NO support" and "Fare-paying services with professional support"? Such like CentOS vs Red Hat Enterprise Linux? If so, are the below right understanding? or am I fundamentally miss understanding? 1. Container Linux - For general users. Free of charge but no professional support. Soon'll be deprecating. 2. RedHat CoreOS - For corporate users. Charged for support and etc. 3. Fedora CoreOS - For general users. Post Container Linux. Free of charge but no professional support.

CoreOS does not include a package manager but my preferred text editor is nano, not vi or vim. Is there any way around this? gcc is not available so its not possible to compile from source: core@core-01 ~/nano-2.4.1 $ ./configure checking build system type... x86_64-unknown-linux-gnu checking host system type... x86_64-unknown-linux-gnu checking for a BSD-compatible install... /usr/bin/install -c checking whether build environment is sane... yes checking for a thread-safe mkdir -p... /usr/bin/mkdir -p checking for gawk... gawk checking whether make sets $(MAKE)... no checking whether make supports nested variables... no checking for style of include used by make... none checking for gcc... no checking for cc... no checking for cl.exe... no configure: error: in `/home/core/nano-2.4.1': configure: error: no acceptable C compiler found in $PATH To put this in context, I was following this guide when I found I wanted to use nano.

On Fedora coreOS there is no file /etc/fstab on the default install. What is the correct place to have partitions automatically mounted on boot?

I am running CoreOS with the root filesystem on a particular SSD device (say /dev/sda) and I want to install Flatcar Linux onto a different SSD device (say /dev/sdb). The reason I am doing this is that /dev/sdb is smaller so I want to turn /dev/sda into a device just for external storage. CoreOS labels the root filesystem partition ROOT, (i.e. /dev/disk/by-partlabel/ROOT is a symlink to the root partition on /dev/sda). However, when I install Flatcar Linux onto /dev/sdb, I will get the same thing (i.e. the root partition on /dev/sdb will also be labelled ROOT -- I could change this of course, but my OCD wants to stick to the same value specified in the documentation ). I plan to change the BIOS settings to prioritise /dev/sdb over /dev/sda when booting so that Flatcar Linux boots by default, but will there be an issue with these clashing partlabels? I would hope that udev (which creates these symlinks as far as I know) would see that the /dev/disk/by-partlabel/ROOT symlink already exists (and refers to the root partition on /dev/sdb) and skips creating the symlink for /dev/sda, but is that actually what happens?

I am getting ready to do a bare-metal install of Fedora CoreOS in an air-gapped environment, and I'm trying to find a resource that lists the tools the distro comes packaged with. For instance, I know I'm going to need apache2-utils and podman once I get on this environment, but I want to check whether I'll be able to install these tools without internet access, or if I get them on a network-facing machine and move them over. Beyond that, what is the best way to find this information for any distro? I've been searching for quite a while and have not been able to find anything definitive other than which container tools are included. This probably sounds like a complete novice question, and while I think I have a pretty good understanding of how a distro's built-in packages work, I may be mistaken. If that's the case, some clarification would be much appreciated.

Using CoreOS (docker preinstalled), I am failing to make two containers communicate together. I am trying to setup a MySql container called by a Gogs container (Git server). So here is what I did: The port is set with 127.0.0.1 so it cannot be accessible from the outside. > docker run --name mysql1 -v /volumedata/mysql/mysql1:/var/lib/mysql -e > MYSQL_ROOT_PASSWORD=PWDHERE -p 127.0.0.1:33061:3306 -d > mysql/mysql-server:latest --character-set-server=utf8 > --collation-server=utf8_general_ci And then I have installed > docker run --name=go-git-server1 -p 10022:22 -p 10080:3000 -v > /data/go-git-server1:/data gogs/gogs Both of them are running when I check it with **docker ps -a** and I can access to the install page of "go-git-server1" without any problem, however when I specify the host address: 127.0.0.1:33061 on the setup page of Gogs, after validating I have this error: > Database setting is not correct: dial tcp 127.0.0.1:33061: getsockopt: connection refused I thought that with the IP and Port given by "docker ps -a" (and already set manually with the initial "docker run") it would have been sufficient for "go-git-server1" container to access the MySql database. Am I missing a step? Is there something else that we need to do so the MySql container can be accessible from the other container? Here is what docker inspect mysql1 gives: docker inspect mysql1 [ { "Id": "c811d29d866ef977eb0cb93a9697bc4afd2a51e828b7757a5ea8962d784f0166", "Created": "2016-07-03T21:55:29.693884299Z", "Path": "/entrypoint.sh", "Args": [ "-p", "127.0.0.1:33061:3306" ], "State": { "Status": "exited", "Running": false, "Paused": false, "Restarting": false, "OOMKilled": false, "Dead": false, "Pid": 0, "ExitCode": 1, "Error": "", "StartedAt": "2016-07-26T18:23:36.144915853Z", "FinishedAt": "2016-07-26T18:23:38.281589339Z" }, "Image": "4e66d61404cc06e3c40c46f5e83bda5a14dda2838b84210c7eb5a3d6e1f7752b", "ResolvConfPath": "/var/lib/docker/containers/c811d29d866ef977eb0cb93a9697bc4afd2a51e828b7757a5ea8962d784f0166/resolv.conf", "HostnamePath": "/var/lib/docker/containers/c811d29d866ef977eb0cb93a9697bc4afd2a51e828b7757a5ea8962d784f0166/hostname", "HostsPath": "/var/lib/docker/containers/c811d29d866ef977eb0cb93a9697bc4afd2a51e828b7757a5ea8962d784f0166/hosts", "LogPath": "/var/lib/docker/containers/c811d29d866ef977eb0cb93a9697bc4afd2a51e828b7757a5ea8962d784f0166/c811d29d866ef977eb0cb93a9697bc4afd2a51e828b7757a5ea8962d784f0166-json.log", "Name": "/mysql1", "RestartCount": 0, "Driver": "overlay", "ExecDriver": "native-0.2", "MountLabel": "system_u:object_r:svirt_lxc_file_t:s0:c724,c935", "ProcessLabel": "system_u:system_r:svirt_lxc_net_t:s0:c724,c935", "AppArmorProfile": "", "ExecIDs": null, "HostConfig": { "Binds": [ "/donnees/mysql/mysql1:/var/lib/mysql" ], "ContainerIDFile": "", "LxcConf": [], "Memory": 0, "MemoryReservation": 0, "MemorySwap": 0, "KernelMemory": 0, "CpuShares": 0, "CpuPeriod": 0, "CpusetCpus": "", "CpusetMems": "", "CpuQuota": 0, "BlkioWeight": 0, "OomKillDisable": false, "MemorySwappiness": -1, "Privileged": false, "PortBindings": {}, "Links": null, "PublishAllPorts": false, "Dns": [], "DnsOptions": [], "DnsSearch": [], "ExtraHosts": null, "VolumesFrom": null, "Devices": [], "NetworkMode": "default", "IpcMode": "", "PidMode": "", "UTSMode": "", "CapAdd": null, "CapDrop": null, "GroupAdd": null, "RestartPolicy": { "Name": "no", "MaximumRetryCount": 0 }, "SecurityOpt": null, "ReadonlyRootfs": false, "Ulimits": null, "LogConfig": { "Type": "json-file", "Config": {} }, "CgroupParent": "", "ConsoleSize": [ 0, 0 ], "VolumeDriver": "" }, "GraphDriver": { "Name": "overlay", "Data": { "LowerDir": "/var/lib/docker/overlay/4e66d61404cc06e3c40c46f5e83bda5a14dda2838b84210c7eb5a3d6e1f7752b/root", "MergedDir": "/var/lib/docker/overlay/c811d29d866ef977eb0cb93a9697bc4afd2a51e828b7757a5ea8962d784f0166/merged", "UpperDir": "/var/lib/docker/overlay/c811d29d866ef977eb0cb93a9697bc4afd2a51e828b7757a5ea8962d784f0166/upper", "WorkDir": "/var/lib/docker/overlay/c811d29d866ef977eb0cb93a9697bc4afd2a51e828b7757a5ea8962d784f0166/work" } }, "Mounts": [ { "Source": "/donnees/mysql/mysql1", "Destination": "/var/lib/mysql", "Mode": "", "RW": true } ], "Config": { "Hostname": "c811d29d866e", "Domainname": "", "User": "", "AttachStdin": false, "AttachStdout": false, "AttachStderr": false, "ExposedPorts": { "3306/tcp": {}, "33060/tcp": {} }, "Tty": false, "OpenStdin": false, "StdinOnce": false, "Env": [ "MYSQL_ROOT_PASSWORD=mypwd", "PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin", "PACKAGE_URL=https://repo.mysql.com/yum/mysql-5.7-community/docker/x86_64/mysql-community-server-minimal-5.7.13-1.el7.x86_64.rpm " ], "Cmd": [ "-p", "127.0.0.1:33061:3306" ], "Image": "mysql/mysql-server:latest", "Volumes": { "/var/lib/mysql": {} }, "WorkingDir": "", "Entrypoint": [ "/entrypoint.sh" ], "OnBuild": null, "Labels": {}, "StopSignal": "SIGTERM" }, "NetworkSettings": { "Bridge": "", "SandboxID": "", "HairpinMode": false, "LinkLocalIPv6Address": "", "LinkLocalIPv6PrefixLen": 0, "Ports": null, "SandboxKey": "", "SecondaryIPAddresses": null, "SecondaryIPv6Addresses": null, "EndpointID": "", "Gateway": "", "GlobalIPv6Address": "", "GlobalIPv6PrefixLen": 0, "IPAddress": "", "IPPrefixLen": 0, "IPv6Gateway": "", "MacAddress": "", "Networks": { "bridge": { "EndpointID": "", "Gateway": "", "IPAddress": "", "IPPrefixLen": 0, "IPv6Gateway": "", "GlobalIPv6Address": "", "GlobalIPv6PrefixLen": 0, "MacAddress": "" } } } } ] I have tried the ip given by ip -4 addr show docker0 | grep -Po 'inet \K[\d.]+' ...instead the 127.0.0.1 that failed, but no, it doesn't work.

As described [here](https://docs.flatcar-linux.org/os/root-filesystem-placement/) , not all partitions of Flatcar Linux's root filesystem support RAID 1 > Other system partitions, such as USR-A, USR-B, OEM, and EFI-SYSTEM, > cannot be placed on a software RAID array What are the implications of this? Suppose the root filesystem is configured with RAID 1, can either drive fail? Or if the drive containing the single copy of the above partitions fails, would the OS fail to function?

I am currently using [Container Linux](https://coreos.com/os/eol/) for my home server and I want to upgrade to [Flatcar Linux](https://www.flatcar-linux.org/) . To do this I plan to use [Ignition](https://docs.flatcar-linux.org/os/root-filesystem-placement/) and configure RAID 1 for the root filesystem. I have two disks dedicated for the root filesystem and the rest form a BTRFS array for extra storage, so I want to make sure not to overwrite the BTRFS disks. The root disks for Container Linux currently register as /dev/sda and /dev/sdb. My understanding is that the names of these disks depends on which Linux kernel you are using and other random boot factors. How can I make sure I pick the right disks in my Ignition configuration? I guess this is a very common issue but I can't find anything specific to Container Linux/Flatcar Linux.

I'm currently in the process of setting up an OKD-Cluster on ESXi (non-production, my own Hardware), following the official documentation on Red Hat's website , but instead of using RHCOS I'm using Fedora CoreOS. So far I've set up the loadbalancer, created DNS entries and generated the ignition configs. I created those on a CentOS 8 VM, and copied them to my Windows 10 workstation for backup. I'm pretty new to ignition, so the only thing I've changed is the URL from https:// ... to http:// ... because I don't want to mess with that in my test environment. But this is where it gets a little strange. This is the content of my master.ign file: "ignition": { "config": { "merge": [{ "source": "http://api-int.openshift..local:22623/config/master " }] }, "security": { "tls": { "certificateAuthorities": [{ "source": "data:text/plain;charset=utf-8;base64," }] } }, "version": "3.0.0" } If I copy that Base64 encoded cert and decode it on my CentOS VM, it generates a (valid-looking) certificate. But if I encode the whole file (which is required by the tutorial ) and let the machines boot with it, I get an error saying that the certificate is not valid and there was something wrong with the decoding (I can pull up the specific log files later). If I try to decode the file by hand and then the certificate, it gets gibberish with invalid characters (object replacement characters and replacement characters). So does anyone have any ideas what my problem might be? Have I missed something? Or maybe I can even omit the security part because I'm using http? (haven't tried that yet, came up with the idea while typing this)

This is a ported Ubuntu core for an arm-based computer board(Nanopi m1): I did write it on SD card, but there is nothing to do with this. No terminal, no options! How can I install something upon this? Are there any other cores? Is it hard to make another Linux ported for this board?

I tried googling around but updating CoreOS seemed to be the only way to go about doing is. I tried doing dnf -y install opensssl in the expectation that installs work the way they work on ubuntu: install if not present and update otherwise. However, dnf isn't installed on this machine. I tried using yum as well, but yum too isn't present. How do I update openssl on this machine?

I work for a company that deploys clustered products using coreos and docker, and as part of our deployment, we automatically start up a few docker containers to expose, among others, a web interface for the client to interact with. The issue I am facing at the moment is that the terminal (be it bare metal, vmware, virtualbox) where coreos is deployed (non-ssh) is very verbose. It dumps all sorts of systemd information, as well as docker daemon output directly to the client-facing terminal. I rebuilt the coreos ISO to include some auto-deployment stuff, and would prefer if there was a way I could turn off this verbosity at ISO level, or even soon after boot (by adding a script to the ISO). I need to find out why this default terminal is used to dump daemon output?
