# Docker Images Repo
|
|
|
|
repo for storage any useful SaaS oriented on containers -> Enjoy!
|
|
|
|
## Docker & Docker Compose Installation
|
|
|
|
firstly you need docker:
|
|
|
|
```bash
|
|
apt-get install docker.io
|
|
yum install docker.io
|
|
pacman -S docker
|
|
```
|
|
|
|
next step is docker-compose installation:
|
|
|
|
```bash
|
|
sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
|
|
sudo chmod +x /usr/local/bin/docker-compose
|
|
docker-compose --version
|
|
```
|
|
|
|
## Docker & Docker Compose Configure
|
|
|
|
you can use docker / docker-compose with sudo but you can add your user to ```docker``` group, and use docker straightly, like that:
|
|
|
|
```bash
|
|
sudo groupadd docker
|
|
sudo usermod -aG docker $USER
|
|
newgrp docker
|
|
```
|
|
|
|
is likely you need rebot for save permission changes.
|
|
|
|
also important thing is configure systemctl for running docker on boot with systemd:
|
|
|
|
```bash
|
|
sudo systemctl enable docker.service && sudo systemctl enable docker
|
|
sudo systemctl start docker
|
|
sudo systemctl status docker
|
|
```
|
|
|
|
otherwise you can disable docker auto runner with systemd:
|
|
```bash
|
|
sudo systemctl disable docker.service && sudo systemctl disable docker
|
|
```
|
|
|
|
## Docker Cleaning
|
|
|
|
you can clean docker objects separetly, but removing every objects are more comfortable:
|
|
|
|
```bash
|
|
docker system prune --volumes
|
|
```
|
|
|
|
## Minikube installation
|
|
|
|
Alternatively you can install minikube and deploy all of docker-compose configurations via k8s
|
|
|
|
```bash
|
|
curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64
|
|
sudo install minikube-linux-amd64 /usr/local/bin/minikube
|
|
```
|
|
|
|
you can start it like that:
|
|
|
|
```bash
|
|
minikube start
|
|
```
|
|
|
|
after that you have to install kubectl separately or use it by minikube facade:
|
|
|
|
```bash
|
|
kubectl get po -A
|
|
|
|
# OR
|
|
|
|
minikube kubectl -- get po -A
|
|
```
|
|
|
|

|
|
|
## Convert Docker-Compose Configs to Kubernetes Resources
|
|
|
|
you can install ```kompose``` for do that:
|
|
|
|
```bash
|
|
curl -L https://github.com/kubernetes/kompose/releases/download/v1.26.0/kompose-linux-amd64 -o kompose
|
|
chmod +x kompose
|
|
sudo mv ./kompose /usr/local/bin/kompose
|
|
```
|
|
|
|
go to particular service directory and execute this one:
|
|
|
|
```bash
|
|
kompose convert
|
|
```
|
|
|
|
after that execute this one:
|
|
|
|
```bash
|
|
kubectl apply -f <output file>
|
|
```
|
|
|
|
```<output file>``` means all of generated files separated by ```,``` like that for e.g.:
|
|
|
|
```bash
|
|
kubectl apply -f frontend-tcp-service.yaml,redis-master-service.yaml,redis-slave-service.yaml,frontend-deployment.yaml,redis-master-deployment.yaml,redis-slave-deployment.yaml
|
|
```
