Cockpit 162 released
by Martin Pitt 21 Feb '18

21 Feb '18

http://cockpit-project.org/blog/cockpit-162.html Cockpit is the modern Linux admin interface. We release regularly. Here are the release notes from version 162. Show pod name and disks of VMs running in Kubernetes ---------------------------------------------------- The KubeVirt Virtual Machines overview now shows the pod of running VMs. Clicking on the name navigates to the pod's detail page. The new "Disks" tab shows information about the emulated QEMU storage devices in the VM, similar to the Machines page. Screenshots: http://cockpit-project.org/images/kubernetes-kubevirt-podname.png http://cockpit-project.org/images/kubernetes-kubevirt-disks.png Thanks to Marek Libra for this feature! Tighten up the default Content-Security-Policy ---------------------------------------------- Cockpit's pages now further restrict their Content-Security-Policy (https://developer.mozilla.org/en-US/docs/Web/HTTP/CSP) to prevent forms and links from accidentally leaking data off-host. An additional benefit is improved privacy, as `Referrer:` headers are no longer sent when following a link in Cockpit to an external site. (One common place where Cockpit links externally is on changelogs in the Software Updates page.) Note that this is *not* an actual security device - once a malicious page runs in Cockpit, it can use the Cockpit API to run arbitrary code on the host. This change is intended as a defense against programming errors. Drop cockpit-subscriptions and cockpit-integration-tests on Fedora ------------------------------------------------------------------ There is a new package "subscription-manager-cockpit" now which supersedes the "cockpit-subscriptions" package that was previously shipped by Cockpit. The cockpit-integration-tests package had been an experiment, was never used in Fedora CI, and requires additional files from Cockpit's upstream git tree to work. Get it ------ You can get Cockpit here: http://cockpit-project.org/running.html Cockpit 162 is available in Fedora 27: https://bodhi.fedoraproject.org/updates/cockpit-162-1.fc27 Or download the tarball here: https://github.com/cockpit-project/cockpit/releases/tag/162 Take care, Martin Pitt

Cockpit on OpenShift deployment
by Marek Libra 19 Feb '18

19 Feb '18

Hi, I'm trying to deploy Cockpit on OpenShift using [1] following [2] but failing to properly expose it. Let's consider minimalistic deployment: # oc version oc v3.9.0-alpha.3+78ddc10 # oc cluster up # oc login -u system:admin # oc adm policy add-cluster-role-to-user cluster-admin admin # oc new-project cockpit # oc status In project cockpit on server https://127.0.0.1:8443 # oc process -f ./openshift-cockpit.template \ -v COCKPIT_KUBE_URL=https://127.0.0.1 \ -v OPENSHIFT_OAUTH_PROVIDER_URL=https://127.0.0.1:8443 | \ oc create -f - The service is deployed, pod is running but I'm not able to access it from browser. What URL is it expected to be available at, please? Are parameters above correct? Do I need to set certificates? How? Using COCKPIT_KUBE_INSECURE=true did not help me. # oc expose service openshift-cockpit will expose it at [3], but when following it, I get error message about malformed request from [4]. Thank you, Marek [1] https://github.com/cockpit-project/cockpit/blob/master/containers/openshift… [2] https://github.com/cockpit-project/cockpit/blob/master/containers/kubernete… [3] http://openshift-cockpit-cockpit.127.0.0.1.nip.io/ [4] https://127.0.0.1:8443/oauth/authorize

Cockpit 161 released
by Martin Pitt 07 Feb '18

07 Feb '18

http://cockpit-project.org/blog/cockpit-161.html Cockpit is the modern Linux admin interface. We release regularly. Here are the release notes from version 161. New VMs can be created on Machines page --------------------------------------- The Machines page now has a "Create New VM" button for installing a new libvirt virtual machine from a local or remote ISO image. It allows the user to set some basic properties such as memory and storage sizes. Thanks to Dominik Perpeet and suomiy for this feature! Screenshot: http://cockpit-project.org/images/machines-create-iso.png VMs running in Kubernetes can now be deleted -------------------------------------------- Cockpit 160 added an initial overview of kubevirt Virtual Machines. This page now got a first action to delete a running VM. Thanks to Marek Libra for this feature! Screenshot: http://cockpit-project.org/images/kubernetes-kubevirt-delete.png Improve LVM volume resizing --------------------------- Cockpit now knows upfront whether shrinking or growing an LVM logical volume is possible, and whether the filesystem needs to be unmounted. Since shrinking and growing are quite different in practice, the Storage page now shows separate "Shrink" and "Grow" buttons. Video: https://www.youtube.com/watch?v=M43yTrJ0jzc Add new Hardware Information page --------------------------------- On the System page the "Hardware" name is now a link to a new "Hardware information" page. For now this shows information about the system name, form factor, CPU, BIOS, and PCI devices. Other types of hardware will be added in future versions. Screenshot: http://cockpit-project.org/images/system-hwinfo.png Rename cockpit-ovirt package to cockpit-machines-ovirt ------------------------------------------------------ The previous package name collided with a package that is already available in Red Hat Virtualization Host. This only affects Fedora, as other operating systems do not ship the Cockpit ovirt extension. Stop advertising and supporting cockpit-bundled jQuery library -------------------------------------------------------------- Cockpit's JavaScript API documentation (http://cockpit-project.org/guide/latest/api-base1-jquery.html) previously had some outdated information about jQuery, suggesting that users of the Cockpit API should always load jQuery, and use the one bundled with `cockpit.js`. This has not been true for a long time, and was just forgotten to be cleaned up. Previously the Cockpit code examples also did that, misleading developers who used them as a starting point for their own modules. Both the documentation and the examples got cleaned up now, and issues got filed on affected GitHub projects. From now on, please use your own jQuery module for your projects instead of cockpit's bundled one. This avoids breaking your project when cockpit's jQuery version gets updated.

Remote management of linux devices
by John Pearson 06 Feb '18

06 Feb '18

I manage a fleet of linux devices and I need a way to send telemtry data(CPU, memory, drives, etc.) from devices to a centralized server and also send commands(linux service restarts for example) from server to devices to execute on the device. I understand Cockpit works great for this. What I need help with: The 15 different linux devices are bare metal boxes in 15 different locations access to WAN with a dynamic IP address. Would Cockpit work for this? In a year the number of devices could jump to 100 so I'm looking for suggestions on best to manage. Thanks.

03 Feb '18

Hello, I'm writing a cockpit package based on the kubernetes modules and i got an error while trying to create replication controllers and services from files: kube-controller-manager[3793]: I0131 20:56:41.083074 3793 event.go:217] Event(v1.ObjectReference{Kind:"ReplicationController", Namespace:"default", Name:"webserver-controller", UID:"52463259-064a- 11e8-b244-086d41bdeb72", APIVersion:"v1", ResourceVersion:"1741601", FieldPath:""}): type: 'Warning' reason: 'FailedCreate' Error creating: No API token found for service account "default", retry after the token is automatically created and added to the service account i'm trying to create the service and replication controller with the following code: $http.get(service.rc_file).then(function(data) { service.json.service = data.data; console.log("Creating RC from JSON: " + JSON.stringify(data.data)); request = new CockpitKubeRequest("POST", link, JSON.stringify(data.data), ""); request.then(function(response) { console.log("Create RC RESPONSE: " + response); }); }); I've checked the kubernetes package and is not clear to me how to create or get the token. Can somebody give me a hand? Thanks, Ivan

Translations
by Tiago Machado 01 Feb '18

01 Feb '18

What is the correct way to submit new translation statements inside the translation files? There are a lot of missing terms in our language (Portuguese) and I would like to add them to the po/pt_BR.po file. Should I just open a PR or there is a procedure for that?
