## Build 

### To build one image

```
docker-compose -f conan-el6-gcc44\docker-compose.yml build
```

### To build an image manually without docker-compose

```
docker build --build-arg http_proxy --build-arg https_proxy --build-arg no_proxy -t conan-el6-gcc44 -f conan-el6-gcc44/Dockerfile .
```

### To build image without docker-compose with specific version of Conan

```
$ docker build --build-arg http_proxy --build-arg https_proxy --build-arg no_proxy --build-arg CONAN_VERSION=2.4.1 -t conan-el6-gcc44 -f conan-el6-gcc44/Dockerfile .
```

```

### To launch one container without docker-compose

```
$ docker run --rm -ti -e http_proxy -e https_proxy -e no_proxy conan-el6-gcc44
```

### To launch one container x86 without docker-compose

```
$ docker run --rm -ti -e http_proxy -e https_proxy -e no_proxy --platform=linux/386 conan-el6-gcc44-x86
```

## Known issues

### BuildKit 
When you build an image that depends of other, you can be unable to get dependency if buildKit is enable
```
 => ERROR [internal] load metadata for docker.io/library/conan-el6-gcc44-x86:latest                                                                                                                          1.5s

### CentOS 6 on WSL2
There is an issue when old Linux distribution as CentOS 6 with Docker on Windows with WSL2

The exit with return code 139
https://github.com/microsoft/WSL/issues/4694#issuecomment-556095344

Create a file %USERPROFILE%/.wslconfig with Unix end lines (LF)
```
[wsl2]
kernelCommandLine = vsyscall=emulate
```

For testing

```
$ docker run -ti centos:6 bash
```
