## Deploy
containerlab (via vscode) & go.
it takes about a minute for the setup to be ready (DHCP etc).
it takes a good minute (with 50 workstations) for the setup to be ready (DHCP etc).
to create a csv of the online-users, run
`echo "IP,host,username,pwd"; cat online-users.txt | awk -F' +' 'BEGIN{OFS=","} {$1=$1; print}'`
on linux-gateway.
## prep workshop
once the lab is deployed and the online-users.txt is built, generate the cards to print out:
### generate CSV
`(echo "IP,host,username,pwd"; cat online-users.txt | awk -F' +' 'BEGIN{OFS=","} {$1=$1; print}') > credentials.csv`
### csv2cards script
```
#!/usr/bin/env bash
# csv2cards.sh → html
CSV=${1:-credentials.csv}
OUT=${2:-cards.html}
# start the document
cat >"$OUT" <<'EOF'
