Docker file

Docker creates image in the same directory as the dockerfile file.

Docker build-t xmh:20190718-f / root/xmh30190718/Dockerfile.

Note: xmh:20190718 cannot be uppercase.

Running image is also in the same directory.

Docker run-p 8088 80-d 8becf9e1d3d5

Mongo docker

1. Build docker images

2. Create a docker container

Docker run-d-p 27018 27017-- name mongo_test mongo# of which 27018 can be changed

Docker run-- name= "flaskForFAW"-- p 4004 flaskForFAW 80-d eeb030de7bda

3. Enter docker

Docker exec-it mongo_test / bin/bash

4. Open mongo

Mongo

5. Create new users

Use admin

Db.createUser ({user: "admin", pwd: "admin123", roles: [{role: "root", db: "admin"}]})

6. Quit

Exit ()

Ubuntu

1. Install Ubuntu system commands:

Docker pull ubuntu

This is an extremely compact system, not even the most basic wget command; so first you have to apt-get update upgrade the system and install the apt-get install wget command

2. Run the command to enter the Ubuntu system:

Docker run-ti ubuntu bash

3. Correct way to exit the system:

Press first, ctrl+p

Press again, ctrl+q

Never use exit or ctrl+d to exit, so the whole system will exit!

4. Share the host directory to the Ubuntu system:

Docker run-it-v / AAA:/BBB ubuntu bash

In this way, the AAA folder in the root directory of the host is mapped to the container Ubuntu, and the two can be shared.

5. Log in to the ubuntu image system in docker:

Docker run-ti ubuntu / bin/bash

# 6866 is the first four digits of IMAGE ID-you can tell which image it is.

6. Exit and then enter ubuntu

1. First use docker ps-a to find the corresponding number of the CONTAINER ID (for example: 0a3309a3b29e)

2. Enter the docker attach 0a3309a3b29e of the system (if there is no response at this time, ctrl+c will enter the ubuntu system)

7. Enter docker

Docker exec-it ID/name / bin/bash

8. Add users to mongo in docker

The common way to add a new user will encounter permission problems.

So log in as admin.

Mongo-- port 27017-u admin-p password-- authenticationDatabase admin

Then add the database

Use faw

Add user

Db.createUser ({user: "FAW", pwd: "CASC", roles: [{role: "readWrite", db: "FAW"}], mechanisms: ["SCRAM-SHA-1"]})

Crontab

Apt-get update

Apt-get install cron
