Install - Server on Offline Linux VM using Podman with Sudoless Access
- Installation Steps
Installation Steps
Take the following steps to install the vFunction Podman Server on an Offline Linux VM with Sudoless Access:
As the Root User Before the Installation
- SSH to the Linux VM where the vFunction Server will be installed
- Confirm that podman and runc are installed. For example:
yum list installed podman runc
- Create the Rootless User if needed and set the Home Directory to the location where the 100gb of Storage exists. For example:
### Replace $USER and $PATH_TO_100GB_STORAGE with the actual values
useradd -m $USER -d /$PATH_TO_100GB_STORAGE
- If a new user was created, create a password for the Rootless User as well. For example:
### Replace $USER with the actual value
passwd $USER
- Confirm that the Rootless User has Sub User IDs that can be used by Podman. If no results are returned, follow these steps to add Sub User IDs
### Replace $USER with the actual value
grep '$USER' /etc/subuid
- Confirm that the Rootless User has Sub Group IDs that can be used by Podman. If no results are returned, follow these steps to add Sub Group IDs
### REPLACE $GROUP with the actual value
grep '$GROUP' /etc/subgid
- Give the Rootless User ownership of the Home Directory where the 100gb of Storage exists. For example:
### Replace $USER, $GROUP and $PATH_TO_100GB_STORAGE with the actual values
chown -R $USER:$GROUP /$PATH_TO_100GB_STORAGE
- Allow the Rootless User to continue running the vFunction Server Containers even after the terminal session has ended. For example:
### Replace $USER with the Sudoless User running the vFunction installation
loginctl enable-linger $USER
As the Rootless User Performing the Installation
- SSH to the Linux VM where the vFunction Server will be installed
- Run to move to the Rootless User’s Home Directory
cd ~
- Create directories for the Podman Containers and the vFunction installation:
### Replace $PATH_TO_100GB_STORAGE with the actual location
mkdir -p /$PATH_TO_100GB_STORAGE/storage tmp measurements db dm
- Start Podman. If the Rootless User cannot restart Podman without Administrative Credentials, follow these steps here
systemctl start podman
podman ps
- Download the latest vFunction Server Podman Installation TGZ
- Move the downloaded vFunction Server Podman Installation package to the Home Directory on the Linux VM
- Unpack the Installation Package
### Replace VERSION with the actual value
tar -xvzf vfunction-server-podman-offline-installation.vVERSION.tgz
- Optional if using HTTPS: Move the chained SSL Certificate Bundle as server.crt and the SSL Key as server.key into the vfunction/etc/sysconfig/vfunction/nginx/certs/
- Open the server-installation.yaml
### Replace $BASE_DIR with the location where the vFunction Installation TGZ was unpacked
vi $BASE_DIR/vfunction/etc/sysconfig/vfunction/installation/server-installation.yaml
- Set the required Configurable Settings
### Sample Yaml with Required Configurable Settings
### Replace /$PATH_TO_100GB_STORAGE with the actual location
server:
host: http://172.17.21.72:1024
org_name: MyOrg
admin:
email: peter@myorg.com
name: Peter
password: Password1!
storage:
database: /$PATH_TO_100GB_STORAGE/db
measurements: /$PATH_TO_100GB_STORAGE/measurements
dm: /$PATH_TO_100GB_STORAGE/dm
- If needed, configure the optional Configurable Settings
- Set the Temporary Container Image Storage location is this was modified as a Prerequisite because there was not 15gb available in /var/tmp:
export TMPDIR=/$PATH_TO_100GB_STORAGE/tmp
- Run the installation script
### Replace $BASE_DIR with the location where the vFunction Installation TGZ was untarred
bash $BASE_DIR/vfunction/opt/vfunction/server-installation/install.sh
