ToolBox

Toolbox with git, wget, curl, nano, netcat and more.

This Docker Image is based on latest AlpineLinux, see Dockerfile and Dockerfile (extended) for more details.

Example for Docker

# start
docker run --rm --name toolbox -d tobi312/tools:toolbox
# exec
docker exec -it toolbox sh
# use (example: check port is open)
nc -zv -w 3 <HOST> <PORT>

Example for Docker-Compose

Create file `toolbox.yml` with this content: (click)

version: '2.4'
services:

  toolbox:
    image: tobi312/tools:toolbox
    #image: tobi312/tools:toolbox-extended
    container_name: toolbox
    restart: unless-stopped
    #user: "1000:1000"  # format: "${UID}:${GID}"
    #entrypoint: [ "/bin/sh", "-c", "--" ]
    #command: [ "while true; do sleep 60; done;" ] 

and then:

# start
docker-compose -f toolbox.yml up -d
# exec (you can use sh or bash)
docker-compose -f toolbox.yml exec toolbox sh
# or
docker exec -it toolbox sh
# use (example: check port is open)
nc -zv -w 3 <HOST> <PORT>

Example for Kubernetes

Create file `toolbox.yaml` with this content: (click)

apiVersion: v1
kind: Pod
metadata:
  name: toolbox
  namespace: default
spec:
  containers:
  - name: toolbox
    image: tobi312/tools:toolbox
    resources:
      requests:
        memory: "128Mi"
        cpu: "0.1"
      limits:
        memory: "512Mi"
        cpu: "0.5"

and then:

# start
kubectl apply -f toolbox.yaml
# exec
kubectl exec -it pod/toolbox -- sh
# use (example: check port is open)
nc -zv -w 3 <HOST> <PORT>

Or example for Deployment.

dnsmasq

dnsmasq is a lightweight dns and dhcp server.

Example for Docker-Compose

Create file `docker-compose.yml` with this content: (click)

version: "2.4"

• instead -e EASYRSA_PKI="/easyrsa/root-ca" you can use in command --pki-dir=/easyrsa/root-ca
• Backup: execute tar cvpzf backup_easyrsa_$(date '+%Y%m%d-%H%M').tar.gz . in data_easyrsa-Folder!
• docker run --rm --name easy-rsa --entrypoint="" -it tobi312/tools:easy-rsa-3.1.7 bash
• linux: copy ca-certs into /usr/local/share/ca-certificates/ and execute dpkg-reconfigure -f noninteractive ca-certificates
