Tag VMs for deployment:
gcloud compute instances add-labels INSTANCE_NAME --zone=ZONE --labels=lc-edr=true --project=PROJECT_ID
Fallback method - Direct SSH/gcloud compute ssh:
gcloud compute ssh INSTANCE_NAME --zone=ZONE --project=PROJECT_ID --command='
curl -o /tmp/lc-installer https://downloads.limacharlie.io/sensor/linux/64 && \
chmod +x /tmp/lc-installer && \
sudo /tmp/lc-installer -i INSTALLATION_KEY && \
rm /tmp/lc-installer
'
Preferred method - Use SSM for managed deployment:
# For Linux instances - single command
aws ssm send-command \
--document-name "AWS-RunShellScript" \
--instance-ids "i-1234567890abcdef0" "i-0987654321fedcba0" \
--parameters 'commands=[
"curl -o /tmp/lc-installer https://downloads.limacharlie.io/sensor/linux/64",
"chmod +x /tmp/lc-installer",
"sudo /tmp/lc-installer -i INSTALLATION_KEY",
"rm /tmp/lc-installer"
]' \
--region REGION \
--output json
# For Windows instances
aws ssm send-command \
--document-name "AWS-RunPowerShellScript" \
--instance-ids "i-abcdef1234567890" \
--parameters 'commands=[
"Invoke-WebRequest -Uri \"https://downloads.limacharlie.io/sensor/windows/64\" -OutFile \"$env:TEMP\\lc-installer.exe\"",
"Start-Process -FilePath \"$env:TEMP\\lc-installer.exe\" -ArgumentList \"-i\", \"INSTALLATION_KEY\" -Wait",
"Remove-Item \"$env:TEMP\\lc-installer.exe\""
]' \
--region REGION \
--output json
Check SSM command status:
aws ssm list-command-invocations \
--command-id "COMMAND_ID" \
--details \
--output json
Check if SSM agent is running:
aws ssm describe-instance-information \
--filters "Key=InstanceIds,Values=i-1234567890abcdef0" \
--output json
Preferred method - VM Run Command (synchronous):
# For Linux VMs
az vm run-command invoke \
--resource-group RESOURCE_GROUP \
--name VM_NAME \
--command-id RunShellScript \
--scripts '
curl -o /tmp/lc-installer https://downloads.limacharlie.io/sensor/linux/64
chmod +x /tmp/lc-installer
sudo /tmp/lc-installer -i INSTALLATION_KEY
rm /tmp/lc-installer
'
# For Windows VMs
az vm run-command invoke \
--resource-group RESOURCE_GROUP \
--name VM_NAME \
--command-id RunPowerShellScript \
--scripts '
Invoke-WebRequest -Uri "https://downloads.limacharlie.io/sensor/windows/64" -OutFile "$env:TEMP\lc-installer.exe"
Start-Process -FilePath "$env:TEMP\lc-installer.exe" -ArgumentList "-i", "INSTALLATION_KEY" -Wait
Remove-Item "$env:TEMP\lc-installer.exe"
'
Note: Azure Run Command is synchronous by default - it waits for completion.
DigitalOcean doesn't have a native deployment service like SSM or OS Config. Use direct SSH:
# Using doctl for SSH access
doctl compute ssh DROPLET_ID --ssh-command='
curl -o /tmp/lc-installer https://downloads.limacharlie.io/sensor/linux/64 && \
chmod +x /tmp/lc-installer && \
sudo /tmp/lc-installer -i INSTALLATION_KEY && \
rm /tmp/lc-installer
'
Note: Requires SSH key configured with the droplet.
Replace INSTALLATION_KEY placeholder with actual key in all commands.
For each VM group (by OS type), execute the appropriate command:
Wait for deployment to complete (varies by platform):
After deployment, verify sensors appear in LimaCharlie:
limacharlie sensor list --online --oid <org-id> --filter "[?iid=='<installation-key-iid>']" --output yaml
Return structured JSON with deployment status for each VM:

After deployment, wait up to 2 minutes for sensors to appear:
# Calculate timestamp

Query for new sensors with the installation key:
limacharlie sensor list --oid OID --filter "[?iid=='INSTALLATION_KEY_IID']" --output yaml
Check if sensors are sending data:
# Calculate timestamps

end=$(date +%s)
limacharlie event list --sid SENSOR_ID --start $start --end $end --oid OID --output yaml
