-# Vuls on Docker
+# Vuls Docker components

-## What's Vuls-On-Docker
+This is the Git repo of the official Docker image for vuls.

- This is a dockernized-Vuls with vulsrepo UI in it.
- It's designed to reduce the cost of installation and the dependencies that vuls requires.
- You can run install and run Vuls on your machine with only a few commands.
- The result can be viewed with a browser
+# Supported tags and respective `Dockerfile` links

-## Setting up your machine
-	
-1. [Install Docker](https://docs.docker.com/engine/installation/)
-2. [Install Docker-Compose](https://docs.docker.com/compose/install/)
-3. Make sure that you can run the following commands before you move on.
+- go-cve-dictionary
+  - [`latest` (*go-cve-dictionary:latest Dockerfile*)]()
+- vuls
+  - [`latest` (*vuls:latest Dockerfile*)]()
+- vulsrepo
+  - [`latest` (*vulsrepo:latest Dockerfile*)]()

-	```
-	$ docker version
-	$ docker-compose version

+This image version is same as the github repository version.

+# Caution

+This image is built per commit.
+If you want to use the latest docker image, you should remove the existing image, and pull it once again.

-## Start A Vuls Container
+1. Confirm your vuls version

- Execute the following command to build and run a Vuls Container
+- go-cve-dictionary

-	```
-	$ docker-compose up -d
-	```
+```console
+$ docker run  --rm  vuls/go-cve-dictionary -v

-## Setting up Vuls
-
-1. Locate ssh-keys of targer servers in (vuls/docker/conf/)
-2. Create and ajust config.toml(vuls/docker/conf/config.toml) to your environment
-	
-	```
-	[servers]
-

+
+# How to use this image
+
+1. fetch nvd (vuls/go-cve-dictionary)
+1. configuration (vuls/vuls)
+1. configtest (vuls/vuls)
+1. scan (vuls/vuls)
+1. vulsrepo (vuls/vulsrepo)
+
+## Step1. Fetch NVD
+
+```console
+$ for i in `seq 2002 $(date +"%Y")`; do \
+    docker run --rm -it \
+    -v $PWD:/vuls \
+    -v $PWD/go-cve-dictionary-log:/var/log/vuls \
+    vuls/go-cve-dictionary fetchnvd -years $i; \
+  done
+```
+
+## Step2. Configuration
+
+Create config.toml referring to [this](https://github.com/future-architect/vuls#configuration).
+
+```toml
+[servers]
+
+[servers.amazon]
+host         = "54.249.93.16"
+port        = "22"
+user        = "vuls-user"
+keyPath     = "/root/.ssh/id_rsa" # path to ssh private key in docker
+```
+
+
+```console
+$ docker run --rm \
+    -v ~/.ssh:/root/.ssh:ro \
+    -v $PWD:/vuls \
+    -v $PWD/vuls-log:/var/log/vuls \
+    vuls/vuls configtest \
+    -config=./config.toml # path to config.toml in docker
+```
+
+## Step3. Configtest
+
+```console
+$ docker run --rm -it\
+    -v ~/.ssh:/root/.ssh:ro \
+    -v $PWD:/vuls \
+    -v $PWD/vuls-log:/var/log/vuls \
+    vuls/vuls configtest \
+    -config=./config.toml # path to config.toml in docker
+```
+
+## Step4. Scan
+
+```console
+$ docker run --rm -it \
+    -v ~/.ssh:/root/.ssh:ro \
+    -v $PWD:/vuls \
+    -v $PWD/vuls-log:/var/log/vuls \
+    -v /etc/localtime:/etc/localtime:ro \
+    -e "TZ=Asia/Tokyo" \
+    vuls/vuls scan \
+    -config=./config.toml # path to config.toml in docker
+```
+
+## Step5. Report
+
+```console
+$ docker run --rm -it \
+    -v ~/.ssh:/root/.ssh:ro \
+    -v $PWD:/vuls \
+    -v $PWD/vuls-log:/var/log/vuls \
+    -v /etc/localtime:/etc/localtime:ro \
+    vuls/vuls report \
+    -cvedb-path=/vuls/cve.sqlite3 \
+    -format-short-text \
+    -config=./config.toml # path to config.toml in docker
+```
+
+## Step6. vulsrepo
+
+```console
+$docker run -dt \
+    -v $PWD:/vuls \
+    -p 80:80 \
+    vuls/vulsrepo
+```
