 ================
 
-Docker image with mongodump running as a cron task
+This is a fork of https://github.com/istepanov/docker-mongodump -- Docker image with mongodump running as a cron task. I added scripts to automatize installation for a backup docker container.
 
-### Usage
+### How To Use
+First you have to build docker image from the repository:
+```docker build -t istepanov/mongodump .```
+After that you can install backup job for your mongodb docker container as follows (basically provide container name as an argument to install-backup.sh script):
+```
+$ docker ps
+CONTAINER ID        IMAGE                         COMMAND                CREATED             STATUS              PORTS                    NAMES

+39cae58c3dc8        mongo:latest                  "/entrypoint.sh mong   4 weeks ago         Up 5 days           27017/tcp                campus2020portal_mongo_1
+$ ./install-backup.sh campus2020portal_mongo_1
+```
+This will run a docker container with cron job installed inside, which will backup mongodb once a day at 1.00 A.M. and save the output to /var/backups/mongodb as a .tar.gz archive. When you run docker via remote access (i.e. access remote docker host), the data will be saved on remote machine!
 
-Attach a target mongo container to this container and mount a volume to container's `/data` folder. Backups will appear in this volume. Optionally set up cron job schedule (default is `0 1 * * *` - runs every day at 1:00 am).
+For configuration options, please, take a look inside the scripts. Crontab schedule is available in crontab file and `0 1 * * *` by default.
 
-	docker run -d \
-		-v /path/to/target/folder:/backup  # where to put backups
-		-e 'CRON_SCHEDULE=0 1 * * *'       # cron job schedule
-		--link my-mongo-container:mongo	   # linked container with running mongo
-		istepanov/mongodump
-
-To run backup once without cron job, add `no-cron` parameter:
-
-	docker run --rm \
-		-v /path/to/target/folder:/backup  # where to put backups
-		--link my-mongo-container:mongo	   # linked container with running mongo
-		istepanov/mongodump no-cron
+To run backup once you can use the following script:
+```
+$ ./run-backup.sh campus2020portal_mongo_1
+```
