If you would like to create a ramdisk within CircleCI you can use the windows program
imdisk which can be installed using the chocolatey package manager which comes preinstalled with the Windows executor.
Below you will find an example config.yml which will install the
imdisk software and then create a ramdisk within the executor.
The issue is that the ramdisk will not be persistent as it will be removed once the machine is stopped.
version: 2.1 orbs: win: email@example.com jobs: build: executor: name: win/default shell: powershell.exe steps: - checkout - run: systeminfo - run: name: "Install imdisk" shell: powershell.exe command: | choco install imdisk - run: name: "Imdisk" command: | imdisk -a -s 512M -m X: -p "/fs:ntfs /q /y"
choco install imdisk will install the imdisk software.
A breakdown of the
imdisk command from the config.yml is given below:
- -a initializes the virtual disk.
- -s 512M is the size, 512 MegaBytes.
The full choices are b, k, m, g, t, K, M, G, or T.
These denote a number of 512-byte blocks, thousand bytes, million bytes, billion bytes, trillion bytes, KB, MB, GB, and TB, respectively.
- -m X: sets up the mount point a.k.a. the drive letter, X:.
- -p "fs:ntfs /q /y" formats the drive.
-p's parameters are actually for Windows' format program.
So, if you want the RAM disk in a different filesystem, just change ntfs to fat (FAT16) or fat32 (FAT32).
