amazon web services - AWS Auto Scaling Multiple Custom AMIs? -


i have several custom amis running control group, i.e. automatically spin them , tear them down @ predefined times. different amis rather multiples of same ami. possible auto scaling api?

let's want create 3 instances, can create them via individual calls cli ec2-run-instances, such

ec2-run-instances ami-1a2b3c4d -k gsg-keypair (more params etc)

ec2-run-instances ami-7d2b3c55 -k gsg-keypair (more params etc)

ec2-run-instances ami-8d2b3c55 -k gsg-keypair (more params etc)

retrieving instance id each call. tag instance part of group:

ec2-create-tags i-bf72dbd2 --tag "purpose=xyz_pdq" (for each of 3 changing instance id on each call)

then, later, can retrieve list of instances tag calling

ec2-describe-tags --filter "resource-type=instance" --filter "key=purpose" --filter "value=xyz_pdq"

iterate thru list , terminate instances

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
