I need to install and set up OpenIAM custom edition using docker in centos VM , I don't want to go for enterprise edition for which docker image is available in OpenIAM git hub through a subscription.
I am aware of the rpm install manually for custom edition that requires other dependencies to install as well for complete set up, but want to automate this through docker. Any idea how I can achieve this?
Just for transparency, I work for OpenIAM.
Our RPM installation requires minimal external dependencies. Additionally, there will be a new release of the Community Edition next month which will be provided via Docker as well. The Enterprise Edition currently supports RPM, Docker and Kubernetes.
We will also be releasing a slew of tutorial videos for v4.1.11 and 4.1.12 in the coming weeks to help users get started.

I was told it's better not to use latest in Docker File, but how can I find alternatives?
According to: https://ubuntu.com/download/desktop the latest version of ubuntu is Ubuntu 22.04.1 LTS but when I go to: https://hub.docker.com/_/ubuntu/tags I see strange tags like: bionic what is that?
and 22.10 this is a future version? how is that possible?
and while I could fine 22.04 I could not find 22.04.1
There are many problems involving the usage of latest tag on a docker image. The application is constantly changing and with it its architecture as well. While pulling an image with the latest tag, you use these changes as well. This may be good in a personal project sometimes but in a large scale application, you dont want your application to change drastically. Example:
While working on a dockerized application, we incorporated db connector to session storage redis db, the connector connected to redis at the start of the application and if it was unsuccessful, the application would not start. Every update/change on the host machine with running application meant deploying redis as well as we were using the latest tag.
22.04 Ubuntu is the latest LTS build, but there also is experimental 22.10 (ref. Ubuntu 22.10
Docker EE installation followed here: https://docs.docker.com/install/windows/docker-ee/#install-docker-ee
for the script install. The uri seems to be broken. looking at download.docker.com it seems you dont have any of the new docker ee releases there (specifically 1809 that I’m looking to upgrade to) our network policies on our docker machines dont allow us to use PSGallery so I can’t follow the Install-Module approach…
Is there anything I can do to update to the latest docker ee?
You can get the direct download urls from this json file.
At the time of writing, the 1809 package zip is here and seems to be the same version that the OneGet provider installs.
The link is actually included under section "Update Docker Engine - Enterprise" on the Docker docs page, but the offline installation should ideally include a method for discovering the url.
Can I install Docker over a server with pre-installed cPanel and CentOS 7? Since I am not aware of Docker, I am not completely sure whether it will mess with cPanel or not. I already have a server with CentOS 7 and cPanel configured. I want to know if I can install Docker over this configuration I mentioned without messing up?
Yes you can install docker over cPanel/WHM just like installing it on any other CentOS server/virtual machine.
Just follow these simple steps (as root):
1) yum install -y yum-utils device-mapper-persistent-data lvm2 (these should be already installed...)
2) yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
3) yum install docker-ce
4) enable docker at boot (systemctl enable docker)
5) start docker service (systemctl start docker)
The guide above is for CentOS 7.x. Don't expect to find any references or options related to Docker in the WHM interface. You will be able to control docker via command line from a SSH shell.
I have some docker containers already running on my cPanel/WHM server and I have no issues with them. I basically use them for caching, proxying and other similar stuff.
And as long as you follow these instructions, you won't mess-up any of your cPanel/WHM services/settings or current cPanel accounts/settings/sites/emails etc.
Not sure why you haven't tried this already!
I've been doing research and working on getting Docker working on cPanel. It's not just getting it to work on a CentOS 7 box but rather making it palatable for the cPanel crowd in the form of a plugin. So far I can confirm that it's absolutely doable. Here's what I've accomplished and how:
Integrate Docker Compose with cPanel (which is somewhat a step
further from WHM)
Leverage the user-namespace kernel feature in Linux so Docker
services can't escalate their privileges (see userns remap)
Leverage Docker Compose so users can build complex services and
start ready apps from the store with a click
Make sure services starting via Docker run on a non-public IP on the
server. Everything gets routed via ProxyPass
cPanel has been gracious to provide a Slack channel for people to discuss this upcoming plugin. I'd be more than happy to invite you if you'd like to be kept updated or to contribute. Let me know!
FYI, there's more info here on https://www.unixy.net/docker if you're interested. Please note that this plugin is in private beta but more than happy to let people use it!
Yes you could, in fact someone else has done it already: https://github.com/mirhosting/cPanel-docker
I want to install docker 1.3.1 on my centos 6.5 environment but I have no idea how to find it in the epel. I'm quite new to docker. Can anyone help me out? Thanks
Clearly stated in the Docker documentation:
Docker runs on CentOS 7.X.
CentOS 6.5 is not CentOS 7.X. Docker is not available for your old operating system.
Furthermore, you didn't give any details about your computer, but you should remain aware that Docker only works on 64-bit systems.
By the way, you should take better care of your computer; in CentOS, the minor version number is updated automatically by the package manager. So the fact that you are two versions behind (CentOS 6 is currently on 6.7) indicates that you are not performing updates to your packages, and could have various security vulnerabilities. You should update your system regularly, by simply running yum update.
I would like to use the Spark-graphX packages available to Neo4j through Mazerunner, however I am an analyst and not a software person. I am running Windows 7 on my laptop and Neo4j 2.3.0, and would like a step-by-step guide explaining how I can set-up Mazerunner for both Community & Enterprise. There's a lot of mention of dockers and containers, and I have no idea what these are, or how to set them up. Simple instructions would be of sooo much help! :)
Docker is primarily Operating System Level Visualization technology designed to run on Unix based systems (Linux,Mac,FreeBSD). Luckily Docker provides a Windows version that sort of does the same thing on Unix.
What happens is, after you have installed Docker, it allows you to run what they call containers which are basically virtual machines on top of your host (Windows 7 Running Docker). This allows you to run services like Neo4j in an isolated environment. Docker also allows you to download and install pre-configured, pre-compiled images of operating systems that usually provide some sort of service or have some software pre-installed.
In your case, I believe all you have to do is:
First install Docker
Use "Docker Compose" to download and install the images.
Continue Reading the Tutorial as you have now installed the required docker images
Note: Some of the operations, like the one in Step 2 will require command-line access and Also the creation of a "docker-compose.yml" so, be sure to visit all the links I have provided. Spend a little time going through them and you should be alright.
