# docker-images-example-bash
Example of a simple bash application using the startx s2i builder [startx/fedora](https://hub.docker.com/r/startx/fedora).
For more information on how to use this image, **[read startx OS image guideline](https://github.com/startxfr/docker-images/blob/master/OS/README.md)**.
## Running this example in OKD (aka Openshift)
### Create a sample application
```bash
# Create a openshift project
oc new-project startx-example-bash
# start a new application (build and run)
oc process -f https://raw.githubusercontent.com/startxfr/docker-images/master/Services/bash/openshift-template-build.yml -p APP_NAME=myapp | oc create -f -
# Watch when resources are available
sleep 10 && oc get all
```
### Create a personalized application
- **Initialize** a project
```bash
export MYAPP=myapp
oc new-project ${MYAPP}
```
- **Add template** to the project service catalog
```bash
oc create -f https://raw.githubusercontent.com/startxfr/docker-images/master/Services/bash/openshift-template-build.yml -n startx-example-bash
```
- **Generate** your current application definition
```bash
export MYVERSION=0.1
oc process -n startx-example-bash -f startx-bash-build-template \
-p APP_NAME=v${MYVERSION} \
-p APP_STAGE=example \
-p BUILDER_TAG=latest \
-p SOURCE_GIT=https://github.com/startxfr/docker-images-example-bash.git \
-p SOURCE_BRANCH=master \
-p RUN_ACTION=run \
-p MEMORY_LIMIT=256Mi \
> ./${MYAPP}.definitions.yml
```
- **Review** your resources definition stored in `./${MYAPP}.definitions.yml`
- **build and run** your application
```bash
oc create -f ./${MYAPP}.definitions.yml -n startx-example-bash
sleep 15 && oc get all
```
- **Test** your application
```bash
oc logs pods
```
## Running this example with source-to-image (aka s2i)
### Create a sample application
```bash
# Build the application
s2i build https://github.com/startxfr/docker-images-example-bash startx/fedora startx-bash-sample
# Run the application
docker run --rm -d startx-bash-sample
# Test the sample application
docker ps
```
### Create a personalized application
- **Initialize** a project directory
```bash
git clone https://github.com/startxfr/docker-images-example-bash.git bash-myapp
cd bash-myapp
rm -rf .git
```
- **Develop** and create a personalized script
```bash
cat << "EOF"
echo "I'm running fo 10 sec ..."; sleep 10; exit;
EOF > run
chmod ugo+x run
```
- **Build** your current application with startx bash builder
```bash
s2i build . startx/fedora:latest startx-bash-myapp
```
- **Run** your application and test it
```bash
docker run --rm -d startx-bash-myapp
```
- **Test** your application
```bash
docker ps
```
