Podman Compose is a tool for easily testing and running multi-container applications. Microcks offers a simple way to set up the minimal required containers to have a functional environment on your local computer. This procedure has been successfully tested with Podman
2.1.1 onto Fedora 33+ and should be OK on CentOS Stream 8+ and RHEL 8+ distributions too.
Then, in your terminal issue the following commands:
Clone this repository.
git clone https://github.com/microcks/microcks.git
Change to the install folder
Spin up the containers in rootless mode using our utility script:
$ ./run-microcks.sh Running rootless containers... Discovered host IP address: 192.168.3.102 Starting Microcks using podman-compose ... ------------------------------------------ Stop it with: podman-compose -f microcks.yml --transform_policy=identity stop Re-launch it with: podman-compose -f microcks.yml --transform_policy=identity start Clean everything with: podman-compose -f microcks.yml --transform_policy=identity down ------------------------------------------ Go to https://localhost:8080 - first login with admin/123 Having issues? Check you have changed microcks.yml to your platform using podman version: podman version 2.1.1 podman run [...]
This will start the required containers and setup a simple environment for your usage.
Open a new browser tab and point to the
http://localhost:8080 endpoint. This will redirect you to the Keycloak Single Sign On page for login. Use the following default credentials to login into the application:
- Username: admin
- Password: 123
You will be redirected to the main dashboard page. You can now start using Microcks.
Rootless or rootfull?
While the rootless mode looks very appealing it does not come as a free lunch.
In particular, in the rootless mode:
- containers have no IP address and no DNS aliases
- port redirection is done in userspace (rootfull mode uses
iptableswhich is faster)
- the overlay storage is done in userspace with
fuse(which is slower than the traditional
So, unless you need high performances or a specific network setup, you can use the rootless mode.
For the Podman support in Microcks, we aim to support both rootless and rootfull mode.
If you’d like to give a try to the rootfull mode, you’ll have to enable the
dnsalias plugin in the default
sudo podman network rm podman sudo podman network create --subnet 10.88.0.0/16 podman
Once done you just need to run the same
run-microcks.sh script with
