(1) Pre-knowledge

(1) Some words

This is the recommended approach. This is the recommended method) manually: manual, manual afterward: then attach: attachment, attention, fixed (` docker attach container ID name ` = > | container into the container) exec: execute (execute: Interactive backstage defend: Maintainer: (docker run-id d: defend) Maintainer: (docker run-ID D: defend) Maintainer: (docker run-ID D: defend) maintainer: MAINTAINER ALTER: alter user 'root'@'%' IDENTIFIED with mysQL_native_password by 'root'; -Blair: Deny the destination premium, navicat premium.Copy the code

(2) the docker command

  • The container related
    • Create open container: docker run -itd –name Container name –link ID of the linked container: the linked alias -p Host port: container port -v Host directory: container directory Image name /bin/bash
    • Docker run -d –name=a –net=host –net=host
    • Exit the current container:docker exit
    • Into the container: docker attach container ID | vessel name Note that if the container has been stop, can’t enter the container, you must first start
    • Into the container and execute the command: docker exec – it container ID | vessel name Execute the command Note that there are invisible to use – id run results
    • Start the container:Docker start container ID | vessel name
    • Stop the container:Docker stop container ID | vessel name
    • Violence stops the container:Docker kill container ID | vessel name
    • Restart the container:Docker restart container ID | vessel name
    • To delete a container:Docker rm -f container ID | vessel name
    • Delete all containers:docker rm -f $(docker ps -qa)-f is mandatory. Running containers can also be deleted
    • Deleting all mirrors:docker rmi -f $(docker iamges -qa)
    • View the container log:Docker logs container ID | vessel name
    • The host copies the file to the container:Docker cp hosting a file or directory container ID | container name: container directoryNote that both copy commands are executed on the host
    • The container copies files to the host:Docker container id | container name: directory or file The host machine directoryNote that both copy commands are executed on the host
    • Port mapping:docker run -it -p 8080:80
    • Submit the runtime container as the image:Docker commit - a = 'author' - m = 'information submitted runtime ID | name of the vessel The new name of mirror
    • !!!!!!!!!!Data volume volume!!!!!!!!!!
      • Docker run-it -v Host path :/ container path
      • If there is no mapped folder in the mapped container, a new folder will be created in the container, but the mapped file will not be placed in the container folder
      • The path following -v must be an absolute path
      • A container can correspond to multiple data volumes, and a data film can be used by multiple containers
    • Data volume container
      • My nugget article – Data volume Container 1
    • volume
      • Docker run-it -v Host path :/ container path
      • If there is no mapped folder in the mapped container, a new folder will be created in the container, but the mapped file will not be placed in the container folder
      • The path following -v must be an absolute path
      • A container can correspond to multiple data volumes, and a data film can be used by multiple containers
    • Image correlation
      • Push the image to the server for my nuggets
      • Docker search ningx check all nginx images on the hub
    • Docker image acceleration: search [container image service] / [image accelerator] in Ali Cloud

(3) Docker install mysql and access

(1) Docker pull mysql, (2) docker run -d --name mysql7 -p 3308:3306 -e MYSQL_ROOT_PASSWORD=root mysql // Docker exec -it mysql7 /bin/bash // docker exec -it mysql7 /bin/bash // Docker exec -it mysql7 /bin/bash -show databases; -show databases; - use mysql; - select host,user,plugin from user; - alter user 'root'@'%' identified with mysql_native_password by 'root'; - Note that all endings are added; Do not forget (6) to link to the database, you can create a new database through Navicat.

(4) Deploy egg to a remote server and access mysql

Git clone [email protected]:woow-wu7/7-react-admin-egg.git (2) run the following command to clone the egg in the root directory: NPM install --production (3) NPM run start (1) NPM install --production (3) NPM run start (3) NPM run start "start": "Egg-scripts start --daemon --title=egg-server-7-react-admin-egg --ignore-stderr" --ignore-stderr Mysql = {client: {host: '49.233.****', port: '3308', user: 'root', password: '****', database: '7-react-admin-egg', }, app: true, agent: false, }; (6) The default port after the egg project is deployed is 7001. (7) Run the following command to test posman: http://49.233.****:7001/api/table-listCopy the code

(二) Dockerfile

(1) docker build

Docker build -f Path to the Dockerfile -t Image name: tag name.

  • Such as:

    • docker build -f /root/work/7/dockerfile/7-web-dockerfile -t nginx .
    • docker build -f $(pwd)/7-web-dockerfile -t mysql .
    • docker build --target node --build-arg NAME=woow -f Dockerfile -t tomcat .

  • This (.) means to specify (the directory of the context in which the image is built).

  • Description:

    • After creating the Dockerfile file, you need to usedocker buildGenerate the mirror
    • Docker buid command parameters
      • -f is short for file. Docker build -f specifies the path to the dockerfile
      • -t is short for tag. Docker build-t specifies the name and tag of the image to be generated
      • Make sure that the Docker build ends with a space.
      • –build-arg=< parameter name >=< value >, which overwrites the environment variable specified by arg in the dockerfile
      • –target=< value of as >, used to explicitly specify the target to be built, e.gdocker build --target node --build-arg NAME=woow -f Dockerfile -t tomcat .

  • Note:

    • $(PWD) must be enclosed in parentheses and cannot be written as $PWD
    • Because. Represents the context environment, so generally when executing Dockerfile, all enter the directory where the Dockerfile file is located,. This is the same as the directory where the Dockerfile is

(1.1) ARG => Docker build in case of [ARG]

  • The (dockerfileARG) represents an environment variable, similar to (ENV)
    • The ARG exists at build image time and no longer exists at container run time, while the ENV still exists at container run time
  • ARG is defined in dockerfile (parameter name or default)
    • The default value can be inDocker build --build-arg=< name >=< value >To cover
  • Refer to the link

(1.2) FROM… as …

  • FROM node as node
  • FROM nginx as nginx
  • If directdocker build --build-arg NAME=woow -f Dockerfile -t tomcat .
    • Two images will be generated
  • If throughdocker build --target node --build-arg NAME=woow -f Dockerfile -t tomcat .
    • Only node images are generated
    • --target nodeUse to explicitly specify the target to be built
ARG NAME=woow_wu7

FROM tomcat as tomcat

RUN echo $NAME

CMD ['cheo', '$NAME']

FROM redis as redis

// docker build --target tomcat --build-arg NAME=woow -f Dockerfile -t tomcat .
Copy the code

(2) Dockerfile syntax

grammar instructions
FROM Reference the base mirroring – from
WORKDIR The current working directory is the default working directory of the container

The WORKDIR directive sets the working directory for any RUN, CMD, ENTRYPOINT, COPY, and ADD directives in the Dockerfile

If WORKDIR does not exist, it will be created, even if it is not used in any subsequent Dockerfile directives
RUN Command executed when creating a mirror – run

For example, RUN yum -y install Vim uses yum to install the Vim package
CMD Set the commands and parameters that are executed by default after the container is started

Such as CMD/bin/bash

– If another CMD command is specified when docker run, the CMD command in Dockerfile is ignored; If more than one CMD is defined, only the last one will be executed

– CMD [“/bin/echo”,”hello docker”]
EXPOSE Exposed port – similar to Docker run-p
MAINTAINER Maintainer – Maintainer

Name < Email or Phone >
LABEL A description of the image, similar to the annotation-label

name=”xxxx” \

date=”xxxx”
ENV Set the environment variables and constants in the container

Reference the value of the environment variable elsewhere by ($)
ARG Defines a variable used during mirror creation, but does not exist after compilation.

When running the Docker build, specify –builder-arg to assign values to variables.
ENTRYPOINT Sets the command to run when the container starts
ADD In addition to COPY, ADD has an additional decompression function
COPY Copy is recommended because add cannot copy tar files

(3) Pits encountered in the use of Docker

  • docker exec
    • docker exec -it node npm -vThe command is executed, but the container is not entered
    • docker exec -it node npm -v /bin/bashThe command is executed, but it does not enter the container
    • Docker exec -it node /bin/bash will enter the container
  • Docker run –link Id of the linked container: alias after the link

(3) Primary – regular deployment react + Egg + mysql

(4) Intermediate – Dockerfile deployment React + egg + mysql

  • Reasons to use Dockerfile:
    • (1) The required configuration can be generated repeatedly because the configuration can be retained
    • (2) Free the complex commands in the process of generating containers. When generating containers, only the commands with short container names need to be generated
  • disadvantages
    • Dockerfile is difficult to achieve the effect of docker run -v, because the volume in Dockerfile can only specify the directory of the container, while it is randomly generated in the host
(1) Write FROM mysql WORKDIR./ ENV MYSQL_ROOT_PASSWORD root EXPOSE 3306 (2) generate image docker build -f Docker run -d --name=mysql_build1 -p 3301:3306 a78d48f2327e (4) Enter the container Docker exec -it mysql_build1 /bin/bash (5) mysql -uroot -proot (6) Access denied for user root@localhost - Solution: show databases; - use mysql; - select host,user,plugin from user; - alter user 'root'@'%' identified with mysql_native_password by 'root'; - Note that all endings are added; Don't forget (7) to link again to Navicat. After linking successfully, you can add tables, design tables, etc. (2) Nginx dockerfile - here nginx and the above myssql is more reasonable to do docker run -v such data volume mapping - and It's hard to implement only in dockerfiles, so skip to docker-compose in 5Copy the code

-Docker-compose: React + egg + mysql

(1) the installation

1, install python-pip yum -y install epel-release yum -y install python-pip docker-compose PIP install docker-compose After the installation is complete, run the docker-compose version spring.dubbo application.name Registry.port command to check whether the installation is successfulCopy the code

(2) The difference between service and project

  • Service: an application container
  • Project: a complete application unit composed of a group of associated application containers

(3) docker-compose common command line command

  • Note :(docker-compose) must be in the path of the docker-compose. Yml file
Docker xompose - v / / docker - compose the version number of the docker - compose up / / start all services docker - compose up - d / / background start all services docker - compose - f // docker-compose2.yml -d up // docker-compose2.yml < /docker-compose2.yml < /docker-compose2.yml < /docker-compose2.yml < /docker-compose2.yml < /docker-compose2.yml < /docker-compose2.yml Docker-compose ps // List all the containers in the project docker-compose ps // List all the containers in the project docker-compose start container name // Docker-compose: docker-compose: docker-compose: docker-compose: docker-compose: docker-compose: docker-compose: docker-compose: docker-compose: docker-compose: docker-compose: docker-compose: docker-compose Docker - compose stop container name | ID)Copy the code
The keyword meaning
version Specifies the version of the compose file, args, and the indispensable field
services (Level 1) Specifies all services
image The specified image
container_name Specifying the container name
working_dir Specifies the working path of the container, equivalent to the WORKDIR in Dockerfile, such as: /

Pay attention to: This path can only be an absolute path
ports Port mapping, equivalent to docker run-p host port: container port

target: Container port

published: host port

abbreviations: – ‘3033:30’

Pay attention toIf target, target, etc., add – first, see the following example
volumes Data mapping

abbreviations: – “.. /nginx/config/conf.d:/etc/nginx/conf.d”

Pay attention to/ / docker-compose: / / docker-compose: / / docker-compose: / / docker-compose: / / docker-compose
environment Set the environment variable, similar to env in Dockerfile

For example,: – MYSQL_ROOT_PASSWORD = root
command The default command executed after the container is started is equivalent to the docker exec -it container command /bin/bash
depends_on Define the container startup sequence
build Specifies the path that contains the build context, or as an object

This object has (context), (Dockerfile), (args)

Context: Specifies the path of the Dockerfile file

Dockerfile: Specifies the name of the dockerfile file. The default is dockerFile

Args: Parameters required by Dockerfile during build

(4) the docker – compose. Yml file
