sudo apt install -y docker.io
sudo systemctl start docker
sudo systemctl enable docker
# kubernetes
sudo curl -s h[......]
#!/bin/sh
if [ x"$1" = x"" ]; then
echo "Usage: $0 private_ip/subnet"
exit -1
fi
IP="$1"
SUBNET="16"
if [ x"$2" != x"" ]; then
SUBNET="$2"
fi
sudo cat <<EOF > /etc/netplan/10-ens7.yaml
network:
version: 2[......]
docker save -o <path for generated tar file> <image name>
docker load -i <path to image tar file>
[......]
例如包含userId的
awk -F '\t' '{for(i=1; i<=NF; i++){if ($i ~ /.*user_id.*/){print $i}}}'
[......]
sort filename | uniq -c | sort -nr
[......]
