A command called cmsd and foo for the cloudmesh shell
Project description
Cloudmesh cmsd
Cloudmesh cmsd is a command to run cloudmesh in a container regardles of the OS. Thus it is extreemly easy to install and use.
cmsd will however use locally installed keys in ~/.ssh
and cloud
configurations stored in ~/.cloudmesh/cloudmesh.yaml
. The yaml file
will be created upon first call of cmsd if it is not available.
How to use cmsd
Important. You must have cms in debug off mode. to use the cmsd command
cms debug off
Prerequesites
- Docker
- python 3.8 or newer
- We strongle recommended to use a python virtual environment
- Install cloudmesh-installer by following the documentation in the Cloudmesh manual
User instalation
$ pip install cloudmesh-cmsd
Developer Source install
For developers it can be installed in an easy fashion with
python3.8 -m venv ~/ENV3
source ~/ENV3/bin/activate
mkdir cm
cd cm
pip install cloudmesh-installer -U
cloudmesh-installer git clone cmsd
cloudmesh-installer git install cmsd
Now you can use the command
cmsd help
...
cmsd --setup
The source code is contained in
cloudmesh-cmsd
cmsd setup
To run cmsd, you would need a configuration directory that is mounted into the container.
Let us call this CLOUDMESH_CONFIG_DIR
. Set CLOUDMESH_CONFIG_DIR
as an environment variable.
For Unix:
> export CLOUDMESH_CONFIG_DIR=<path to CLOUDMESH_HOME_DIR>
For Windows:
> set CLOUDMESH_CONFIG_DIR=<path to CLOUDMESH_HOME_DIR>
NOTE:
CLOUDMESH_CONFIG_DIR
path must not have in any spaces.- Clarification for Windows users:
- For example
C:\.cloudmesh
will work, so doesC:\Users\gregor\.cloudmesh
, but notC:\Users\gregor von Laszewski\.cloudmesh
)- Make sure that the drive of the
CLOUDMESH_CONFIG_DIR
is granted file access in Docker settings
Run setup. If you are running setup on an empty CLOUDMESH_CONFIG_DIR
, you
will be asked to key in some details that are required for the setup, such as
profile details, Mongo DB credentials, etc.
> cmsd --setup
Run the following command to see if the cloudmesh-cms-container
is running!
Additionally, check CLOUDMESH_CONFIG_DIR
contains the cloudmesh.yaml
file.
> cmsd --ps
Run the following to verify if the configurations you entered have been
properly reflected in the cloudmesh.yaml
file.
> cmsd config cat
cmsd usages
- To stop the containers, use
cmsd --stop
. - To start/restart the containers, use
cmsd --start
. - To clean the containers (remove stopped containers), use
cmsd --clean
. - To log into the running
cloudmesh-cms-container
, usecmsd --shell
.
MongoDB and Mongo client connections
cmsd is running an official MongoDB container from Docker Hub. Refer here.
Mongo server container is bound to 127.0.0.1:27071
port. Therefore you can use
any Mongo client to explore the database by connecting to this port.
Example usecase - Creating a vm in AWS
Create an AWS account and add the authentication information in the
CLOUDMESH_HOME_DIR/cloudmesh.yaml
file. Refer Cloudmesh Manual - AWS
Set cloud to aws
> cmsd set cloud=aws
Set AWS key name
> cmsd set key=<key name>
Boot a vm with the default config
> cmsd vm boot
End user deployment
Please uese a python virtualenv as to not interfere with your system python. Activate your python venv. Next just call
pip install cloudmesh-cmsd
This will install a command cmsd
in your environment that you can use
as in place replacement for the cms command.
The containers are called
cloudmesh/cms
cloudmesh/mongo
