Foreword
In today's container concept more and more popular, .Net Core project can also be cross-platform deployment, then think under Sql Server can not it? Of course it is possible. This article is to introduce today Docker deployment configuration and connection Sql Server . Based on Centos7 .
Configuring Docker link Sql Server
Prerequisite (at least 2 GB of disk space of at least 2 GB of the RAM ). We now begin the installation configuration:
Docker Hub query and find the introduction of the Microsoft SQL Server.
Then on the basis of this docker pull mirroring
docker pull mcr.microsoft.com/mssql/server:2017-latest
View mirror and allow this image
docker images
sudo docker run -e "ACCEPT_EULA=Y" -e "SA_PASSWORD=MyPassWord123" -p 1433:1433 --name sql1 -d mcr.microsoft.com/mssql/server:2017-latest
And then see whether to allow successful
Docker ps -a
This will not only allow appear next chart success, display UP ( if that fails, by docker logs a container name to view the error log )
Then here we configure the SQL Server, then we enter the actual container operations.
sudo docker exec -it sql1 "bash" /opt/mssql-tools/bin/sqlcmd -S localhost -U SA -P "MyPassWord123"
Then you can now perform routine database operations, and execute the input command Go End
Create a library
CREATE DATABASE TestDB
Use the library, create a table
USE TestDB CREATE TABLE Inventory (id INT, LastName NVARCHAR(50), FirstName NVARCHAR(50))
Lookup table
Select * from Inventory
User-created table query
select name from sysobjects where type = 'U'
System table sysobjects saved are database objects , wherein the type indicates the type of the various objects, comprises :
U = user table
S = system table
C = CHECK constraints
D = Default or DEFAULT constraint
F = FOREIGN KEY constraint
L = log
FN = scalar function
IF = internally fitted table function
P = Stored Procedures
PK = PRIMARY KEY constraints (type K )
RF = Replication filter stored procedure
TF = Table function
TR = Trigger
UQ = UNIQUE constraint (type K )
V = view
X = Extended stored procedure and associated object information.
Other configurations
First, change the sa login password
sudo docker exec -it sql1 /opt/mssql-tools/bin/sqlcmd -S localhost -U SA -P "MyPassWord123" -Q 'ALTER LOGIN SA WITH PASSWORD="MyPassWord456"'
Second, the data retention
-
- Loading of host data volume directory
docker run -e 'ACCEPT_EULA=Y' -e 'MSSQL_SA_PASSWORD=MyPassWord456' -p 1433:1433 -v /var/opt/mssql -d mcr.microsoft.com/mssql/server:2017-latest
-
- Using the data volume container
docker run -e 'ACCEPT_EULA=Y' -e 'MSSQL_SA_PASSWORD=MyPassWord456' -p 1433:1433 -v sqlvolume:/var/opt/mssql -d mcr.microsoft.com/mssql/server:2017-latest
Third, remove or unload the container
Delete container: Docker RM container name
Remove the mirror: Docker rmi mirror name
Exit container ; Ctrl + D
Fu Chi when the deposit lofty, Muxian Xian, absolutely lust, abandoned suspect delay, so that the end for Chi, the mortgage then be kept, Ceran have a sense; forbearance flexion and extension, to the fine, wide consultation to ask, in addition to too stingy, although remain flooded, what harm Fun in the United States, hang in bad.
If recounts Qiangyi, meaning not generous, only mediocre stagnation in the vulgar, silently beam in love, forever channeling volt mediocre, dirty can not help but to carry on.
